Consider the following carbocations (I) Cl3C+ (II) Cl2CH+ (III) ClCH (IV) CH The stability sequence follows the order
A.IV > I > II < III
B.I < II < III < IV✓ Correct
C.IV < I < III < II
D.IV < II < I < III
Explanation
Chlorine is an electron withdrawing group hence it decreases the stability of carbonium ion. Therefore, the correct order is 4 > 3 > 2 > 1.
