This organic chemistry video tutorial explains how to name esters. It discusses the iupac nomenclature of esters including the common names as well and the rules that go with it. It contains plenty of examples and practice problems including esters with branches and complex substituents plus esters with other functional groups such as alcohols, alkyl halides ketones, and amines. It shows you how to tell which group has more priority and how to count the number of carbon atoms to determine what the parent name of each portion should be. The examples in this video also include benzene rings, diesters, and halides.

Thank you very much. Carboxylic acid, Sulphonic acid and acid anhydride have higher priority than ester. So please make a video on that one when ester is a prefix (when these above mentioned functional groups are present). It will be very helpful.

I have a question about the one at 4:30 -- Why is it Butyl Propanoate and not Propyl Butanoate? Is it because the longer chain's name has to go first?

I think if you use "-dioate" then it will automatically be on the first carbon and the last carbon so it doesn't need "1,5"

@martinsimbeye9119 2 года назад

the exact reason i came to the comment section

@OreoWaffles44 2 года назад

because the ester takes priority? you number the carbons going away from the ester. thus 3rd carbon and not the 2nd.

No, FG gets the priority and the carbon just after oxygen is counted the first.

@stephenwa7417 2 года назад

19:57 can someone explain this part

@hlohi3550 2 года назад

In that example, first we take the part in which the two oxygens are present and then the other part in which oxygens are absent (i.e. the ethyl). Now, in the oxygen containing part, we take and number the longest chain (including the Carbon of ester). It comes out that on the 4th Carbon, chlorine is present as a prefix called chloro and on the 5th Carbon, double bonded oxygen is present. That Carbon+double bonded oxygen is called ketone (i.e. -C=O), which is here being called a prefix. Remember this, that despite being a functional group, the ketone here is being used as prefix, and the prefix for ketone is called 'oxo'. This is because, the functional groups have priority order in which the 1st priority is given to -COOH group, then -SO3H, then acid anhydride and then, 4th comes this Ester. Ketone has lower priority among these and that's why when a lower priority group (here Ketone) is attached to a higher priority group (here ester), then it is used as a prefix. I recommend you to remember the priority order of functional groups. Now coming to the prefix, they are written according their alphabetical order. So, here it is 4-Chloro-5-oxo ('C' comes before 'O'), NOT 5-oxo-4-chloro. Therefore, the name Ethyl 4-Chloro-5-oxo heptanoate. Hope this helps!

@jonathanvallejo1368 6 лет назад

16:30 i think is 2-methyl butyl ethanoate NOT 3-methyl butyl ethanoate because when naming a long hydrocarbon chain we need to start from the side where the first substituent is found the closest. Keep up the good work Sir..... and please reply if im wrong

@rwayle 5 лет назад

The butyl chain is numbered as carbon 1 being the one attached to the oxygen.

How do you name this? CH3-(CH2)8-C..what is the iupac name for this?

@levipotter9373 4 года назад

13:50 why couldn’t it be methyl isobutanoate?

@div_yam2304 4 года назад

isobutane is not an iupac name i think

@OreoWaffles44 2 года назад

there's no such thing as isobutanoate. butane being 4 carbons, iso being a methyl but on which middle carbon, 2 or 3? thus no such thing. you could say isopropanoate, but i guess just to clarify things a little simpler 2-methylpropanoate.

@johnfei434 5 лет назад

I think you forgot to count the carbon atom from the double bonded oxygen

@aldrichibia8302 5 лет назад

There's a 2 because the methyl is attached to the second carbon...

@OreoWaffles44 2 года назад

LOL yeah you're right! because the methyl couldn't be attached to the carbonyl group because it would make it a carbanion, and if the methyl was on the 3rd carbon it would be butanoate XD i guess just for clarification. That was good though LOL
