Vedclass · Answer

(C) The bond angle depends on the repulsion between lone pairs and bond pairs,as well as the electronegativity of the central and terminal atoms.$1$. For $H_2O$,the bond angle is $104.5^{\circ}$.$2$. For $F_2O$,the bond angle is $102^{\circ}$. The electronegative $F$ atoms pull electron density away from the oxygen,reducing the repulsion between bond pairs.$3$. For $Cl_2O$,the bond angle is $109.5^{\circ}$. The large size of the $Cl$ atoms and their lower electronegativity compared to $F$ leads to significant lone pair-bond pair and bond pair-bond pair repulsions,resulting in a larger bond angle.$4$. For $H_2S$,the bond angle is approximately $92^{\circ}$ due to the larger size of the $S$ atom and the lack of hybridization (Drago's rule).Comparing these values,$Cl_2O$ has the largest bond angle. Therefore,option $(C)$ is correct.
