Question
Among the following mixtures, dipole-dipole as the major interaction, is present in
A.
$$KCl$$ and water
B.
benzene and carbon tetrachloride
C.
benzene and ethanol
D.
acetonitrile and acetone
Answer :
acetonitrile and acetone
Solution :
Acetonitrile $$\left( {\mathop {C{H_3}}\limits^{\delta + } - C \equiv \,\mathop N\limits^{\delta - } } \right)$$ and acetone
both are polar molecules, hence dipole-dipole interaction exist between them. Between $$KCl$$ and water ion-dipole interaction is found and in Benzene ethanol and Benzene-Carbon tetra chloride dispersion force is present
