Vedclass · Answer

(C) The bond angle of $H_2S$ $(92^\circ)$ is smaller than that of $H_2O$ $(104^\circ 31')$.According to the $VSEPR$ theory,as the electronegativity of the central atom decreases,the bond pairs move further away from the central atom,reducing the repulsion between them and consequently decreasing the bond angle.In $H_2O$,the central atom is $O$ (more electronegative),and in $H_2S$,it is $S$ (less electronegative).Therefore,the Reason statement is incorrect because the bond angle actually increases as the electronegativity of the central atom increases (due to bond pairs being closer to the central atom,increasing repulsion).Thus,the Assertion is correct,but the Reason is incorrect.

Assertion : Bond angle of $H_2S$ is smaller than $H_2O$.
Reason : Electronegativity of the central atom increases,bond angle decreases.
