Just like `H_(2)O`, there are two lone pairs in `Cl_(2)O` molecule. But bond angle in `Cl_(2)O` is `111^(@)`. Explain.

Explanation

(i) comparison of electrons present in the valence shell in Cl in `Cl_(2)O` and H in `H_(2)O`
(ii) comparisons of size between chlorine and hydrogen
(iii) comparison of the valence electronic configuration between hydrogen and chlorine
