Match the species

(i) (e);

The shape of H₃O⁺ is Tetrahedral. The hybridization is sp³.

(ii) (a);

As Ethylene has double bond in its structure.

So, Ethylene is linear in shape. The hybridization is sp.

(iii) (b);

ClO^-₂ is angular in structure due to lone pair and bond pair repulsion.

(iv) (c);

NH⁺₄ is tetrahedral in shape and the hybridization of N is sp³.
