Consider ‘n’ is the number of lone pair of electrons present in the equatorial position of the most stable structure of ClF₃. The ions from the following with ‘n’ number of unpaired electrons are

Equatorial Lone Pair in ClF3 | JEE Main PYQ | Chemical Bonding

A. V³⁺

B. Ti³⁺

C. Cu²⁺

D. Ni²⁺

E. Ti²⁺

Choose the correct answer from the options given below:

(A) B and D Only

(B) A, D and E Only

(D) A and C Only

Correct Answer: A, D and E Only

Explanation

ClF₃ has sp³d hybridization with T-shaped geometry. Two lone pairs occupy equatorial positions to minimize repulsion.

Thus, n = 2 lone pairs in equatorial positions.

Ions having two unpaired electrons are V³⁺, Ni²⁺ and Ti²⁺.
