1.	Consider the following carbocations. (i) Cl_(3)overset(+)(C) (ii) Cl_(2)overset(+)(C)H (iii) ClCH_(2)^(+) (iv) overset(+)(C)H_(3) The stability sequence follows the order :
Answer» `(iv) lt (i) lt (II) lt (iii)` `(i) lt (ii) lt (iii) lt (iv)` `(iv) lt (i) lt (iii) lt (ii)` `(iv) lt (ii) lt (i) lt (iii)` Solution :Cl due to its -I effect further intensifies the +ve CHARGE and thus DESTABILIZES the carbocation. Thus, as the number of Cl atoms INCREASES, the stability further decreases. Thus, option (b) is CORRECT.
