Which bond do you expect to be stronger in each of the following cases and why ?
(i) ` H - H , Cl - Cl (ii) O _(2), N_(2) (iii) F - F , Cl - Cl `

Explanation

(i) H - H is stronger because of smaller size of H - atoms .
(ii) ` N-= N` is stronger because it contains a trople bond while ` O_(2)` contains a bouble bond ` (O = O)` .
(iii) ` Cl - Cl` is stronger becausa irepulsions betweens the two F-atoms in ` F_(2)` are larger ono account of greater
electrons density around F-atom due to smaller size ans hence greater repulsions between the two F-atoms .
