AIPMT 2008: The correct order of increasing bond angles in the following triatomic species is (A) NO2- < No2+ < No2 (B) NO2- < No2 < No2+ (C) NO2+ < N Note: The bond pairs are usually represented by a solid line, whereas the lone pairs are represented by a lobe with two electrons. C. H 2 S NH 3 SiH 4 BF 3. In OF2, the bonding electrons are nearer of F atom because of higher electronegativity, so the repulsion between the lone pairs exceeds that of bonding pairs, resulting in decrease of bond angle. Have you registered for the PRE-JEE MAIN PRE-AIPMT 2016? M99 (1) When CH4, NH3, H2O, are arranged in order of increasing bond angle, what is the correct order? a) NO2–, NO2, NO2+ b) NO2, NO2–, NO2+ c) NO2+, NO2, NO2– d) NO2, NO2+, NO2– Which has the largest bond angle? When the bond angle values of the given compound are arranged based on increasing order it gives: 103.1 <104.5 <110.9 <112 Thus when the compounds with corresponding values are arranged it gives the following order: The bond angle should be 120o but actually, it is 132o. Let's start with NH3...
