Nitriles can be converted to 1° amines by reaction with LiAlH4. Mechanism
(i) Hydride nucleophile attacks the electrophilic carbon in nitrile to form imine anion. (ii) Hydrolysis of amine derivative. 2-hydroxy-2-methyl propionitrile on acidic hydrolysis gives
2-hydroxy-2-methylpropionic acid. Mechanism The last step of dehydration takes place in presence of H2SO4 to form 2-methylacrylic acid.
2-methylacrylic acid is the product (B). Hence, correct answer is (c).
