# Which of the following is an example of super octet molecule? Option 1) CIF3 Option 2) PCl5 Option 3) IF7 Option 4) All of these

As we learnt in

Exception to octet Rules -

1. species with odd number of electrons :  $NO,\:NO_{2}$

2. Incomplete octet for the central atom  :  $LiCl,\:BeH_{2}\:and \:BCl$

3. Expended octet for the central atoms :   $PF_{5},\: SF_{6} \:and\:H_{2}SO_{4}$

-

Let's check the lewis structure of each option

Clearly, all of the central atoms in above compounds have more than 8 electrons in their outermost shell i.e. have a super actet.

Option 1)

CIF3

This is incorrect option

Option 2)

PCl5

This is incorrect option

Option 3)

IF7

This is incorrect option

Option 4)

All of these

This is correct option
