Which of the following pairs can form tertiary amide?
a.CH3NH2+ CH3(CH2)3COOH
b.(CH3)2NH + CH3(CH2)3CHO (
CH3)3N + CH3(CH2)3CHO
d.(CH3)2NH + CH3(CH2)3COOH
The reaction happening is illustrated below
So, we need to have only two degree amine needs to be reacted with carboxylic acid to form tertiary amide.
Hence the 2 degree amine will be (CH3)2NH and the carboxylic acid possible in this case CH3(CH2)3COOH
Hence the correct answer is Option d
Note - Post any doubts/queries in comments section.
