Question

Compounds $A$ and $C$ in the following reaction are $CH_3CHO {->[(i) CH_3MgBr][(ii)H_2O]} (A) {->[H_2SO_4, \Delta ]} (B)$ ${->[{\text{Hydroboration oxidation}}]} (C)$

• A. identical
• B. positional isomers
• C. optical isomers
• D. functional isomers

Answer 1

Answer: (B)

positional isomers

Answer 2

$CH_{3}CHO { ->[{(i) CH_{3}MgBr}][{(ii) H_{2}O}] }$
${ ->[{H_{2}SO_{4}}][{\Delta}] } \underset{\text{Propene (B)}}{{CH_{3}?CH}} =CH_{2}{ ->[Hydroboration \, oxidation]}\underset{\text{Propan-l-ol (C)}}{{CH_{3}?CH_{2}?CH_{2}OH}}$
