Question

Which of the following has least bond angle?
(3) Oxy
(1) CH.
(2) BF
(3) H₂O
(4) NHZ
Which of the following is most stable?​

Answer 1

Explanation:

All the compounds involve sp

3

hybridization. The bond angles for different compounds vary because of the presence of lone pairs. The bond angle in NF

3

is 102

o

. It has only one lone pair.

The bond angle in PF

3

is 96

o

. It has only one lone pair.

The bond angle in PH

3

is 94

o

. It has only one lone pair.

Boh H

2

and H

2

Se have two lone pairs. Se is less electronegative than S. Hence, the electron pair will be less drawn towards Se than S. In S, since, the electron pairs are more towards S, there will be more repulsion and hence greater bond angle than Se. The bond angle in H

2

Se is 91

o

. The bond angle in H

2

S is 92.3

o

C. H

2

Se has least bond angle.

Answer 2

Answer:

H20 has the least bond angle amongst all.
