Question

The angular shape of water molecule is due to:

• A. high electron affinity of oxygen.
• B. very high repulsions between lone pair and bond pair of electrons.
• C. very high repulsion between lone pair and lone pair electrons.
• D. small size of hydrogen.

Answer 1

The correct option is C very high repulsion between lone pair and lone pair electrons.

In $BeC{l}_2$ ,there is no lone pair of electron. It forms linear structure.

In $H_{2}O$, very High repulsion of lone pair and lone pair electrons give $H_{2}O$ to vent or angular type of shape.
