Vedclass · Answer

(A) The bond angle in hydrides of group $16$ elements depends on the electronegativity of the central atom. As the electronegativity of the central atom decreases down the group $(O > S > Se > Te)$,the bond pair-bond pair repulsion decreases. Also,the size of the central atom increases,which leads to a decrease in the bond angle. Therefore,the bond angle follows the order: $H_2O (104.5^{\circ}) > H_2S (92.1^{\circ}) > H_2Se (91^{\circ}) > H_2Te (90^{\circ})$. Thus,$H_2O$ has the maximum bond angle.

In which of the following is the bond angle maximum?
