Question

What type of intermolecular attraction exist in the pair of methanol and acetone?

Answer 1

1).  n-hexane and n-octane , are neutral and non-polar straight chain molecules which are attached together by the London dispersion force (loosely van der waal's force) of attraction.

2). I2 and CCl4 , are also non-polar molecules so they have dipole/ induced dipole interaction and so they have London dispersion force of attraction.

3).  In, NaClO4 and water, NaClO4 is ionic molecule which produnes sodium and chlorate ions in water and water is polar solvent, so they will have an ion-dipole interaction forces.(via H-bonding)

4.) Methanol and acetone, both are polar and so the intermolecular force of attraction will be dipole-dipole interaction.

5.)Acetonitrile and acetone  are also polar so, they will have dipole-dipole interaction.
