1) NO 2) NO2

3) ClO2

4) N O2 4

Answer 1

THE ANSWER IS HERE....

.

NO2

.

.

.

Nitrogen dioxide is the chemical compound with the formula NO2 . Again, nitrogen dioxide does not follow the octet rule for one of its atoms, namely nitrogen.

The total number of valence electrons is 5+2(6)=17

There is the persistent radical character on nitrogen because it has an unpaired electron.

ClO 2

A Lewis structure shows ClO 2 has a total of 2×6+7=19 valence electrons, or 9 electron pairs and a lone electron.

Cl is the central atom. The molecule ClO 2 has an odd number of valence electrons.

NO

14 valence electrons in your trial structure.

The valence electrons you have available are: 1N+1O=1×5+1×6=11.

The molecule NO, NO 2 and ClO 2 has an odd number of valence electrons.
