Correct Answer: 2. (b)
Solution:
- The major product formed in the reaction is as follows :
Primary alcohol readily oxidised to corresponding carboxylic acid with oxidising agent, chromium trioxide $\left(CrO _3\right)$ in acidic medium.
$-OH$ group of carboxylic acid get substituted by $-Cl$ in presence of $SOCl _2$ (Thionyl chloride).
