Question

Which has the least bond angle
(a) NH₃
(b) BeF₂
(c) H₂O
(d) CH₄

Answer 1

hey mate here is your answer

104.5°

It's H20 cause it's bond angle is 104.5° which is lowest among all. ☛ Considering the measure of bond angles we find that the bond angle of water (H2O) is the least. We know that the repulsion between lone pairs is greater than repulsion between lone pair and bond pair is greater than the repulsion between bond pairs.
