Question

Which of the following compounds is expected to be most basic?

• A. Aniline
• B. Methylamine
• C. Hydroxylamine
• D. Ethylamine

Answer 1

The correct option is D Ethylamine

Due to positive inductive effect of alkyl group, N-atom of amines acquires partial -ve charge and thus electron pair can be easily donated. Hence, most basic compound is Ethylamine $\left(C_2{H}_{5}N{H}_2\right)$ as +I effect of ethyl group is more than methyl followed by hyrdoxy group.
Therefore, option (d) is correct.
