2. Write the structure for each IUPAC name. a. (R)-Butane-1,2,4-triol b. Ethers can be named by naming each of the two carbon groups as a separate word followed by a space and the word ether. Systematic (IUPAC) names for ethers use the more complex group as the root name, with the oxygen atom and the smaller group named as an alkoxy substituent. NEWS CRYPTOCURRENCY TODAY

So eth, meth, prop, propyl, or it's actually propane. So this is our longest. And then we look at this methoxy group right here. And I call this a methoxy group, because I have the o. That gives us the oxy. And I just have a methyl group right here. So this is methoxy. You remember that meth is the prefix for just having only one carbon. We add the oxy because that oxygen is there. And it's attached to the two carbons on the propane chain, no matter what direction you start naming from, or numbering from.

One, two, three. So this is 2-methoxypropane. Let's do another one. Let's do one more. And I think you'll get the gist of at least the reasonably simple ethers to name. So let's put a ring over there. And then that's attached to an oxygen. And then we have another carbon chain right here. And then we have another carbon chain right there. Let me just copy and paste that so that I don't have to redraw it.

So let me copy and paste. All right. So let's do the common name first. That always tends to be a little bit more fun. So on this side, we have one, two, three, four, five, six carbons in a cycle. This right here on the left hand side is a cyclohexyl group.

This on the right hand side, we have one, two, three. This is just a straight-up propyl group. And so when you name the ether, you just put these two groups in alphabetical order, and you add an ether at the end. So it's cyclohexyl. C comes before p. So it's cyclohexyl propyl. Let me get that shade of yellow right. Cyclohexyl propyl ether. So you look for the longest carbon chain here.

In this case, it's going to be the cyclohexane right here. We have one, two, three, four, five, six carbons there. We only have one, two, three there. So this is kind of our backbone. So we write down cyclohexane. No double bonds, so it's a hexane. So that's the cyclohexane right there.

If you just had these three carbons, it would be a propyl. But this is not just three carbons. It's three carbons and then an oxygen. So we would call it a propoxy. So this is propoxy group. And you don't have to number it because it can just be attached to any of these carbons. It would essentially be the same molecule. So you can just call this propoxy cyclohexane. Let me make it a little bit closer to the cyclohexane. Propoxy cyclohexane. But once again the common name is what you're more likely to see.

Now that we've named a few of them, let's think a little bit about their properties. What we've seen already is that-- and we've used it several times, especially in our Sn2 reactions and things like that-- places where we didn't want protons floating around. We used actually diethyl ether. And in general ethers do make for good solvents. They tend to be fairly unreactive. So good solvents. Especially when you're looking for an aprotic solvent.

Remember, aprotic means you don't have hydrogens that can kind of lose their electron to maybe an electronegative atom like an oxygen. And then the proton just floats around, and then can go and react with other things. This does not have any hydrogens directly bonded to an oxygen in any of these cases. So it is an aprotic solvent. And because it doesn't have any hydrogens bonded to the oxygen, you also have no hydrogen bonding.

And just as a bit of a review, you know that in water you have the situation-- let me draw some water molecules-- in water you have the situation where the oxygen hogs the electrons. So it has a partial negative charge. Hydrogen gets its electrons hogged or taken away, or it spends less time with them.

So it has a partial positive charge. So this oxygen will have a partial negative charge. And so the hydrogens with the partial positive charge are attracted to the oxygens with the partial negative charge. And you have this hydrogen bonding. And this hydrogen bonding makes water. It pulls the molecules together. So you need to put more energy into it for it to either melt, or for it to actually boil. And for the molecules to kind of get ripped away from each other.

And that's also true with alcohols. Alcohols only have one hydrogen to each oxygen, but they still have the hydrogen bonding going on. In the case of ethers, there is no hydrogen bonding. I'll represent each of the carbon chains with an R and an R. I'll write R prime right here to show that it could be a different carbon chain than this right here.

Students can make use of the write-up here to understand the topic or even revise it before their exam. They can find many other such topics important for their boards and competitive exams for free on this website.

What are Ethers? Ethers belong to the class or group of organic compounds with an ether group comprising an oxygen atom connected to either two alkyl or aryl groups. Ethers have a similar structure to that of alcohol, whereas both Ethers and Alcohols have a similar structure to that of water. One hydrogen atom of a molecule of water is replaced by an alkyl group in alcohol, whereas coming to the ether, both the hydrogen atoms are replaced either by alkyl or aryl groups.

Ethers Classifications Let us now discuss the ethers classifications. Based on their attached substituent groups, ethers can be classified into two categories, generally. They are listed below. Symmetrical Ethers If two identical groups are attached to either side of an oxygen atom, then it is referred to as symmetrical ethers.

These are also known as Simple Ethers. Examples are diethyl ether, dipropyl ether, dimethyl ether, and more. Asymmetrical Ethers If two different groups are attached to either side of an oxygen atom, it is said to be asymmetrical ethers. These are also known as Mixed Ethers.

Examples are methyl phenyl ether, ethyl methyl ether, and more. The majority of the compounds having a similar structural formula were known by different names earlier, depending on the regions they were synthesized.

Synthesis and cleavage of ethers Video transcript We've already touched on ethers in several videos.

Anderlecht vs qarabag betting expert football	You have to put less heat into the system for these molecules to break away from each other, because they aren't attracted to each other as much. And you don't have to number it because it can just be naming ethers practice to any of these carbons. Sugars contain some of the functional groups we have illinois betting Note the alcohol groups present in the structures and how monosaccharide units are linked to form a disaccharide by formation of an ether. The Ethers Nomenclature topic has been explained in a very detailed way here. So common names, which utilize two separate words indicating each side of the ether, predominate: This structure is named by IUPAC rules as Methoxybutane.

William o neil canslim investing services	Since nitrogen has 5 valence shell electrons it typically forms 3 bonds naming ethers practice other atoms and has one lone pair of electrons. And then you look at the other carbon group right over there. Occasionally the common name mercaptan is still used to describe members of this organic family. Thus, it becomes very important for students to understand Ethers Nomenclature really well. The IUPAC nomenclature of ether works better for the compounds with additional functional groups, because the other functional groups can be described in the root name. These names will seem odd as you first learn them and you might find pronunciation unclear or difficult.

So you can just call this propoxy cyclohexane. So we call this 1-ethoxyethane. So you call this-- let me just write this down-- that is also an ethyl group. Alcohols only have one hydrogen to each oxygen, but they still have the hydrogen bonding going on. You look for the longest chain.
