Which of the folowing have undistorted octahedral structures:(1) `SF_(6) (2) PF_(6)^(-) (3) SIF_(6)^(2-) (4) XeF_(6)`
Select the correct answer using the codes given below

A

`2, 3 and 4`

B

`1, 3 and 4`

C

`1, 2 and 3`

D

`1, 2 and 4`

Text Solution

Verified by Experts

The correct Answer is:
c
`XeF_(6)` has distorted octahedral structure. Xenone in `XeF_(6)` undergoes `sp^(2)d^(3)` hybrization giving pentagonal in which one axis is occupied by a lone pair.
