Question

The major product formed in the following reaction is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

(c)
effects. So, the $\pi$ bond polarizes in the direction of the $-CHO$ group. Hence, $H^{+}$ connects $C_2$ and $Cl$ to $C_3$.
The above compound is less stable as the positive charge further increases on $C_2$ due to -I effect of $-CHO$ and thus it is destabilized.
The above compound is more stable as $-CHO$ is away from positively charged carbon.
So, the product is an anti-Markonikoff's product.
