Vedclass · Answer

(C) The bond angle in hydrides of group $16$ elements depends on the electronegativity of the central atom.As we move down the group,the electronegativity of the central atom decreases,which causes the bond pair electrons to move further away from the central atom.This results in a decrease in bond pair-bond pair repulsion,leading to a smaller bond angle.Therefore,$H_2O$ has the largest bond angle $(104.5^\circ)$ compared to $H_2S$ $(92.1^\circ)$,$H_2Se$ $(91^\circ)$,and $H_2Te$ $(90^\circ)$.

Which of the following hydrides has the largest bond angle?
