Which of the following interaction lies in the range of 8-42kH/mol?

Answer»

`H_(2)..H_(2)O`
`HCl..HCl`
`F^(-)…HF`
`HCN…NH_(3)`

SOLUTION :(a)`H_(2)…H_(2)O` Dipole-induced dipole interaction (van der waal.s force) ENERGY < 8kJ/mol
(b) `H-Cl…H-Cl`Dipole-dipole interaction (van der waal.s force) energy < 8kJ/mol
(c) `F^(-)….HF` Ion-dipole H-bond (van der waal.s force) energy < 42kJ/mol
(d) `HCN....NH_(3)` H-bond energy ranges from 8-42kJ/mol.
