WebDec 15, 2024 · In ester, an OR group replaces the OH group of a carboxylic acid. When naming the ester, the name of the R in the OR group is stated first, followed by the name of the acid, with “oic acid” replaced by “oate”. As a net result, the R in the OR is regarded as the “substituent”, even though it is not. WebFeb 28, 2024 · The amide functional group is to amines as esters are to alcohols. Confusingly, the word “amide” is also used to refer to the conjugate base of amines , such as sodium amide ( NaNH 2) and lithium di- isopropyl amide ( LDA ). The latter are sometimes differentiated by referring to them as “amide bases”.

Esters derived from carboxylic acids and alcohols contain a carbonyl group C=O, which is a divalent group at C atom, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, carboxylic acid esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier.
