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. Among molecules of HCl, which of the following forces are present.

Answer»

Interaction between two HCl MOLECULES is found to be greater than 8kJ/mol
Weak dipole-dipole interaction
Weak ion-dipole interactions
All of above

Solution :`overset(DELTA+)(H)-overset(delta-)(C)overset(E)(…)overset(delta+)(H)-overset(delta-)(Cl)`. The bondenergy (E) between two `H-Cl` molecules, caused by dipole-dipole interaction is not found to be in the range of unsymmetrical H-bond ENERY, RATHER it is less than 8 kJ/mol, hence this interation is CALLED weak dipole-dipole interaction.
