Which of the following statements is incorrect

Options

A. `ClF_(3)` has T-shape
B. In `SF_(4)`, F-S-F equatorial bond angle is less than `120^(@)`
C. In `[I Cl_(4)]^(-), Cl-I-Cl` bond angle is `109^(@)`
D. Shape of `I_(3)^(-)` molecule is linear

Answer

C

Explanation

(i) `ClF_(3) sp^(3)d` hyb with 2 lp , so .T. shape
(ii) In `SF_(4)` due to lp–bp repulsion equitorial bond angle is less than 120.
(iii) In `[ICl_(4) ]^(-) sp^(3)d^(2)` hyb. with two lp. shape square planar, bond angle `90^(@)`
(iv) In `I_(3)^(-) sp^(3)d` hybridisation with 3lp, shape linear
