Among the following mixiture dipole-dipole as the mojor interaction is present is

Options

A. Benzene and ethanol
B. Acetonitrile and acetone
C. KCl and water
D. Benzene and carbon tetrachloride

Answer

B

Explanation

Compounds with many polarized bonds (where the elements have different electronegativities, like C - O `C - N, C = O` etc.) Tend to have large dipole moments like acetone `(CH_3 - overset(O)overset(||)C - CH_3)` and acetonitrile `(CH_3CN)` have appreciable dipoles.
