Q84.
Ans: option d.
Why not option c or e?
Dear Student,
Bond angles of following compounds are :
H 2 O → 104 .
5 ° H 2 S → 92 . 5 °
N H 3 → 106 . 5 °
PH3 → 93 . 5 ° ,
H2Se → 91°

5 ° H 2 S → 92 . 5 °
N H 3 → 106 . 5 °
PH3 → 93 . 5 ° ,
H2Se → 91°
- Since, in the 'lone pair-lone pair' and 'lone pair-bond pair' repulsions are reduced due to the larger size of sulphur atom. Thus, it has the smallest bond angle.
- While, in other cases like repulsions are greater due to smaller size. Thus, their bond angle is larger.
- And in case of H2Se its bond angle is 91° , smallest
