Which of the following molecules is formed without following the octet rule?

A

`SF_6`

B

`IF_7`

C

`BeCl_2`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
In `SF_6` and `IF_7`, the central atoms S and I, respectively, have expanded valence shell while in `BeCl_2`, the central Be atom has an incomplete octet. Thus, all these molecules violate the octet rule.
