Question

The correct order of bond angle in no2 no2+ no2-

Answer 1

Hey mate

hope this will helpful for you

NO3- , NO2- NO2. and NO2+

NO2- < NO3- < NO2 < NO2+

For NO2-, the molecule is bent but we have 1 lone pair on nitrogen. Lone pair electron repulsion is more than the bonding electrons so the bond angle will be less than 120o.

In NO3-, there is no lone pair of electrons, all are bonding pairs leading to an ideal bond angle of 120o.

In NO2, the one lone electron exerts a less repulsion than a lone pair of electrons, so two bonding oxygen atoms are able to spread out more leading to bond angle greater than the ideal of 120o.

In NO2+, there is no lone pair, only bond pairs so the molecule is linear leading to a bond angle of 180o.

Answer 2

Answer:

Order of bond angle

NO2 + greater than NO2 greater than NO2 minus

Explanation:

Since NO2 + has in hybridization of SP with zero lone pair and a linear geometry

NO2 who has one lone electron wit and hybridisation of SP2 the one lone electron has less repulsion.. therefore giving a greater bond angle

NO2 minus has one lone pair of electron.
