Question

The number of isomeric primary amine possible for the formula $C_3{H}_{9}N$ :

• A. 2
• B. 3
• C. 5
• D. 6

Answer 1

Answer: (A)

2

The following primary amines are possible for $C_3{H}_{9}N$

(i) $C{H}_3-C{H}_2-C{H}_2-N{H}_2$ propyl amine

(ii) $C{H}_3-\underset{|}{CH}-C{H}_3$ $2-$aminopropane (Isopropyl amine)

$N{H}_2$

$\therefore 2$ primary amines are possible.
