Which of the following molecules would be expected to be square planar?
1. `NH_3` 2. `XeF_4` 3. `SF_4` 4. `ICl_(4)^(-)` : only 1, 2 and 3 are correct, only 2 and 3 are correct, only 3 and 4 are correct, only 2 and 4 are correct

A

only 1, 2 and 3 are correct

B

only 2 and 3 are correct

C

only 3 and 4 are correct

D

only 2 and 4 are correct

Text Solution

Verified by Experts

The correct Answer is:
D
In `N_2^(o+)` there is one unpaired electron in bonding MO (ie, `sigma2p_z^(1)`) 55. Both `XeF_4` and `ICl_4^(-)` has `sp^3d^2` hybridized central atoms with two lone pairs on each, giving square planar shape.
