Which of the following is a characteristic feature of esters?
A
Presence of a carbonyl group bonded to an amino group
B
Presence of a carbonyl group bonded to a thiol group
C
Presence of a carbonyl group bonded to an alkoxy group
D
Presence of a carbonyl group bonded to a hydroxyl group
Verified step by step guidance1
Understand the structure of an ester: Esters are organic compounds derived from carboxylic acids where the hydroxyl group (-OH) is replaced by an alkoxy group (-OR).
Identify the functional groups involved: Esters contain a carbonyl group (C=O) bonded to an alkoxy group (R-O). This is a key characteristic feature of esters.
Differentiate esters from other functional groups: Unlike esters, amides have a carbonyl group bonded to an amino group (NH2), and thiol esters have a carbonyl group bonded to a thiol group (SH).
Recognize the incorrect options: A carbonyl group bonded to a hydroxyl group forms a carboxylic acid, not an ester.
Conclude with the correct characteristic: The presence of a carbonyl group bonded to an alkoxy group is the defining feature of esters.
