Hydrogen bond is the given to the relatively weak secondry interaction

1.	Hydrogen bond is the given to the relatively weak secondry interaction between a hydrogen atom bound to an electronegative atom and another atom which is also generally electronegative and which has one or more lone pairs and can thus acts as a base. We can give the follwoing generalized representation of hydrogen bond. overset(delta-)(X)-overset(delta+)(H)...Y Bond dissociation energy of H-bond ranges from 8 and 42kJ/ol, and the most commonly encountred hydrogen bonds are O-H...O, N-H...O and F-H..E. Q.Whichof the following interaction has energy between 8-42kJ/mol?
Answer» `NA^(+):C Cl_(4)` `CHCl_(3):Br^(-)` `C_(6)H_(6):C Cl_(4)` `H_(2)O: HCN` Solution :`Na^(+):C C_(4)`: ion-induced dipole `lt8`kJ/mol `CHCl_(3):Br`: Weaker ion-dipole `lt8`kJ/mol `C_(2)H_(6)`: London dipersion FORCES`lt8`kJ/mol `H_(2)O:HCN`: Unsymmetrical H-bond :8-42kJ/mol
