# The maximum bond angle in the hydrides of group 16 elements is in Option 1) $H_{2}O$ Option 2) $H_{2}T_{e}$ Option 3) $H_{2}S_{e}$ Option 4) $H_{2}S$

As we learnt in

Bond angle of hydrides of oxygen family -

All these hydrides are angular melocules and the bond angle H-X-H (X is O,S,Se,Te)

decreases from H2O to H2Te

-

The bond angle in the hydrides of the group 16 decreases as we go down the group. As electronegativity falls down the group, the tendency of the central atom to attract bond pair of electrons falls thus making lone pair - lone pair repulsion more important and thereby reducing the bond angle.
