Question

Give reason for varied bond angle of ch4 h20 and nh3 molecule

Answer 1

$\red{\huge{Here\:is\:your\:Answer}}$

$\large{\underline{Reason}}$

$\boxed{\blue{Bond\:Angle\:/Number\:of\:Lone\:pair\:on\:central\:Metal\:Atom}}$

So by this concept-
angle order will be - CH4>NH3>H20
◆CH4 has no Lone pair
◆H20 has 2 lone pair
◆NH3 has 1 lone pair.
