Solution
The correct options are
A sec-Butyl
B n-Butyl
CH3−CH2−CH2−CH2−MgBr+CH3OH⟶CH3−CH2−CH2−CH3+CH3OMgBr
In this reactions the Grignard reagent acts as base while methanol release acidic H so acid base reaction takes place.
So R can be both A and B which will give n-butane.
While in option C and 3 carbon atoms which won't give n-butane as a product,
Option A and B both are correct.
