Question

The major products A and B in the following set of reactions are : vfHkfØ;kvksa ds fuEufyf[kr lsVksa esa eq[; mRikn A rFkk B gSa % A LiAlH4 H3O+ OH CN H3O+ H2SO4 B

(A) A = OH NH2 , B = COOH
(B) A = OH NH2 , B = OH CHO
(C) A = OH OH , B = OH CHO
(D) A = OH CHO , B = OH CO2H

Prashant Kotian · Accepted Answer

Correct answer: A. OH CN LiAlH4 H3O OH NH2 (LiAlH4 reduces - CN to - CH2 - NH2) OH CN H2SO4 H3O COOH (H2SO4/H3O Hydrolyses –CN to –COOH) Alcohol undergoes elimination reaction inpresence of H2SO4 / H3O+
