Question

Bond angle in Nh3 is more then in H2O . justify ​

Answer 1

Answer:

Explanation:

NH3 has a bond angle of 107.

NH3=5+3x1=8

Each hydrogen atom is linked to the nitrogen atom. This leaves out one lone pair.

H2O has a bond angle of 104.5.

H2O=1x2+6x1=8

Same as NH3

Each hydrogen atom is linked to the oxygen atom. They cannot be double bonded because the hydrogen shell only allows 2 electrons which is already "filled" with the first covalent bond. There are thus 2 lone pairs on the oxygen atom. The lone pairs has electron repulsion spreading the bonds further apart.
