Question

A primary amine has amino group $(-N{H}_2)$ attached to :

• A. A primary carbon atom only
• B. A secondary carbon atom only
• C. A tertiary carbon atom only
• D. A primary, secondary or tertiary carbon atom

Answer 1

The correct option is D A primary, secondary or tertiary carbon atom

$\text{A primary amine has amine group}$

$(-{NH}_2)\text{attached to a primary,}$

$\text{secondary or tertiary carbon atom}$

$\text{because a primary amine group is}$

$\text{directly bonded to one carbon of}$

$\text{any hybridization in the following}$

$\text{way}$

$R-C{H}_2-N{H}_2$ primary amine attach with

primary carbon

${\text{(R)}}_2{\text{CH - NH}}_2\text{primary amine attach with}$

$\text{secondary carbon}$

$R_3-N{H}_2$ primary amine attach with

ternary carbon.
