1.	The strength of the covalent bond in H_(2) , F_(2) and HF is in the order
Answer» `H-HgtF-FgtH-F` `H-FgtF-FgtH-H` `H-FgtH-HgtF-F` `F-FgtH-FgtF-F` SOLUTION :`H-F gt H-H gt F-F` Bond strengths `(KJ MOL^(-1)) ` 566436126 This is because they involve s-p,s-s and p-p OVERLAP respectively.Greater the overlap , stronger is the bond .
