Question

Which of the following species contain at least one atom that violates the octet rule?

• A. $O-Cl-O$
• B. $F-Xe-F$
• C. Both of these
• D. None of these

Answer 1

Answer: (C)

Both of these

Octet rule is violated in both compounds $O-Cl-O$ and $F-Xe-F$. Both compounds are example of expanded octet, in which the central atom has more than 8 valence electrons.

In $O-Cl-O$, $Cl$ atom has 9 valence electrons.

In $F-Xe-F$, $Xe$ atom has 10 valence electrons.
