A

phenylmethanamine

Text Solution

Verified by Experts

The correct Answer is:
B
N- methyl methanamine `(CH_(3))_(2)NH` is a secondary amine whereas all other are examples of primary amine. Secondary amines are more basic than either primary or tertiary amines because their conjugate acids possess the best combination of alkyl and hydrogen substituents to permit stabilization both by electron release from alkyl group and by solvation due to hydrogen bonding.
