Question

In the reaction sequence $CH_3 CH_2 - CH_2Br$ ${\to[Mg][{\text{Dry ether}}]}$ $A$ ${\to[CH_3CHO]}$ $B$ ${\to[H_3O^+ ]}$ $C$ the product $'C'$ is

• A. $1$ -propanol
• B. $2$ -butanol
• C. $3$ -butanol
• D. $2$ -pentanol

Answer 1

Answer: (D)

$2$ -pentanol

Answer 2

$CH_3CH_2CH_2Br {\to[Mg][\text{dry ether}]} \underset{(A)}{CH_3CH_2CH_2MgBr} {\to[CH_3CHO]}$

Hence, the product $'C'$ is (D): $2$-pentanol
