Examine the following structures:
Which of the following statement is correct:

$(A) CH_3-C-OH;$

$(B)CH_3-C-NH_2$

0%
$A$ is tertiary alcohol while $B$ is tertiary amine
0%
$A$ is primary alcohol while $B$ is primary amine
0%
$A$ is tertiary alcohol while $B$ is primary amine
0%
$A$ is primary alcohol while $B$ is tertiary amine

Explanation

A is tertiary alcohol becuase the $OH$ group is attached to a tertiary carbon atom (carbon attached to three other carbon atoms) while B is primary amine where nitrogen is attached to one alkyl chain.

Hence option A is correct.
