Answer:

(1)H2O2

Explanation:

The sulphur atom in sulphur dioxide is sp

-hybridization, and it is a V-shaped molecule.

In NH 4

Cl, all the bonds are polar.

In HCN, the bonds are polar.

In hydrogen peroxide, O−O bond is non-polar and O−H bonds are polar.

In CH 4, all the four bonds are non-polar.

Therefore, the correct option is 1
