Which of the following is a functional isomer of ethylamine, $CH X_{3} CH X_{2} NH X_{2}$ ?

A $CH X_{3} - NH - CH X_{3}$
B $C X_{6} H X_{5} NH X_{2}$
C $CH X_{3} NH X_{2}$
D $(CH X_{3}) X_{3} N$

Answer: A

Ethylamine is a primary amine,

C X_{2} H X_{7} N

. Dimethylamine has the same formula but is a secondary amine, so it is a functional isomer (amine degree). Methylamine is

CH X_{5} N

, trimethylamine

C X_{3} H X_{9} N

and aniline

C X_{6} H X_{7} N

.
