Vedclass · Answer

(D) All given molecules involve $sp^3$ hybridization. $NH_3$ and $PH_3$ have one lone pair,while $H_2O$ and $H_2S$ have two lone pairs.As the number of lone pairs increases,the bond angle decreases due to increased lone pair-bond pair repulsion.Comparing $H_2O$ and $H_2S$,the electronegativity of $O$ is higher than that of $S$.In $H_2S$,the bond pair electrons are further from the central atom,leading to less bond pair-bond pair repulsion,resulting in a smaller bond angle of approximately $92^o$ compared to $104.5^o$ in $H_2O$.

Which of the following molecules has the smallest bond angle?
