Question

which has highest bond angle no2, no2-, no2+​

Answer 1

Explanation:

जो उच्चतम बंधन कोण है no2 no2 no2 +

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.
