Trans esterification is the process of :
conversion of an aliphatic acid to ester
conversion of an aromatic acid to ester
conversion of one ester to another ester
conversion of an ester into its components namely acid and alcohol
The correct sequence of base strengths in aqueous solution is :
(CH3)2NH > CH3NH2 > (CH3)3N
(CH3)3N > CH3NH2 >(CH3)2NH
(CH3)3N > CH3NH2 = (CH3)2NH
(CH3)2NH > (CH3)3N > CH3NH2
A.
(CH3)2NH > CH3NH2 > (CH3)3N
The order of base strength of amines in aqueous solution is as:
(CH3)2NH > CH3NH2 > (CH3)3N
Tertiary amine is less basic than primary and secondary amine due to steric effect of three methyl group present on nitrogen atom.
