Question

Suggest the most important type of intermolecular attractive interaction in the following pairs: n-Hexane and n-Octane

Answer 1

Inter-molecular attractive interaction in n-hexane and n-octane

• Van der Waals interactions are present between the two .
• This interaction is primarily responsible for these intermolecular forces
• The two molecules of the same material (though electrically neutral) are brought together
• The nonbonding electrons of both overlap each other and result in the repulsive force due to the presence of the surface electron.

Hence Van der Waals interactions are present between n-hexane and n-octane
