The pair of species with similar shape is

A

`PCl_(3),NH_(3)`

B

`CF_(4), SF_(4)`

C

`PbCl_(2), CO_(2)`

D

`PF_(5),IF_(5)`

Text Solution

Verified by Experts

(a) Both `PCl_(3)" and "NH_(3)` have pyramidal shape, since both have `sp^(3)`-hyboridisation and one lone pair of electrons. In cntrast, all other pairs have difference hybridisations and hence, different shapes , I.e. `CF_(4)` has `sp^(3)` while `SF_(4)` has `sp^(3)` d-hybridisation, `PbCl_(2)` is ionic while `CO_(2)` has sp-hybridisation, `PF_(5)` has `sp^(3)`d while `IF_(5)` has `sp^(3)d^(2)`-hybridisation.
