suggest the most important type of intermolecular attractive interaction in the following pairs.

(i) n-hexane and n-octane and CCl₄

(ii) NaCIO₄ and water

(iii)methanol and acetone

(iv) acetonitrile (CH₃CN) and acetone (C₃H₆0).

 Solution

 (i)

n-hexane and n-octane and CCl₄  both are non polar so that they have Weak vander Waal's intermolecular interaction or London dispersion forces

(ii)

Both n-hexane and n-octane and CCl₄ are non polar so that they have Weak vander Waal's intermolecular interaction or London dispersion forces

(iii)

On dissociation NaCIO₄ gives Na⁺ and ClO4^- ions in solution and water is a polar solvent so that there are  strong ion-dipole interaction

(iv)

Both are polar molecules hence they have dipole- dipole interaction

(v)

Both are polar molecules hence they have dipole- dipole interaction
