Question

The angle between two covalent bonds is minimum in
(a) CH₄
(b) C₂H₂
(c) NH₃
(d) H₂O

Answer 1

as H2O has two lone pairs so It repels thebond pairs much more and makes bond angle shorter of 104.5 degrees and as NH3has one lone pair that repels the three bondpair but not much effectively and strongly as two lone pairs of water repel the bond pair so the bond angle between hydrogen atom of ammonia is 107.5 
C2H2 has bond angle 180 degree and CH4 has bond angle 109.7 degree.
So among them H2O has minimum bond angle.

Answer 2

Answer:

H2O has minimum angle between two covalent bonds..

Explanation:

1 - H2O is firstly covalent compound among following ...

2 - Due to lone pair repulsion there is a minimum bond form between

two covalent bonds ...
