Question

How many primary amines are possible with the formula $C_4{H}_{11}N$?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

The possible primary amine with the formula $C_4{H}_{11}N$ are

(i) ${CH}_3{CH}_2{CH}_2{CH}_2{NH}_2$

(ii) ${CH}_3\stackrel{\stackrel{{CH}_3}{|}}{CH}-{CH}_2-{NH}_2$

(iii) ${CH}_3-\stackrel{\stackrel{{CH}_3}{|}}{\underset{\underset{{NH}_2}{|}}{C}}-{CH}_3$

(iv) ${CH}_3-{CH}_2-\underset{\underset{{CH}_3}{|}}{CH}-{NH}_2$
