$H_2S$

Vedclass · Answer

(B) The bond angles are as follows: $CH_4$ has a bond angle of $109.5^o$. $NH_3$ has a bond angle of $107^o$. $H_2O$ has a bond angle of $104.5^o$. $H_2S$ has a bond angle of approximately $92^o$. As the electronegativity of the central atom decreases,the bond pair-bond pair repulsion decreases,leading to a smaller bond angle. Since $S$ is less electronegative than $O$,the bond angle in $H_2S$ is the smallest.
