Question

CH4 NH3 and H2O all are AB4 type . explain the reason for difference for bond angle and geometries

Answer 1

Answer:

CH4 HAS HIGHEST BOND ANGLE FOLLOWED BY NH3 AND H2O

REASON BEHIND IT IS LONE PAIRS PRESENT IN NH3 AND H2O

in CH4 there is no lone pair

In NH3 there is one lone pair

in H2Othere is two lone pairs

Explanation:

lone pair-bond pair replusion is more than bond pair-bond pair replusion
