Question

The following compound can be classified as N-N dimethyl propanamine, N-methyl aniline and aniline

• A. Primary, secondary, tertiary
• B. Primary, tertiary, secondary
• C. Secondary, tertiary, primary
• D. Tertiary, primary, secondary (5) None of these

Answer 1

(5)

Sol. Because

N-N dimethyl propanimine

$\underset{3^{o}\text{ amine}}{\overset{CH_{3}}{\overset{|}{CH_{3} - N - CH_{2} - CH_{2} - CH_{3}}}}$

N -Methyl aniline $\rightarrow \overbrace { 2 ^ { \circ } \text { amine } } ^ { \mathrm { NH } - \mathrm { CH } _ { 3 } }$

aniline → $1^{o}$amine.
