Among the following mixtures, dipole-dipole as the major interaction, is present in
Benzene and ethanol
acetonitrile and acetone
KCl and water
benzene and carbon tetrachloride.
As we learnt in
Dipole moment(µ) -
IT is vector sum of all the individual bond moments
- wherein
It is denoted by a small arrow with a tail on the positive centre and head pointing towards negative centre
Molecule Type of interaction
Benzene Vandin waal force
Ethanol dipole- dipole interaction
Acetonitrite dipole- dipole interaction
KCI Ionic bond
H2O dipole - dipole interaction
CCI4 Vandin waal force
Between Acetonitrite and Acetoe the force of intraction is dipole - dipole Interaction.
Dipoledipole interactions occur among the polar molecules. Polar molecules have permanent dipoles. The positive pole of one molecule is thus attracted by the negative pole of the other molecule. The magnitude of dipoledipole forces in different polar molecules is predicted on the basis of the polarity of the molecules, which in turn depends upon the electronegativities of the atoms present in the molecule and the geometry of the molecule ( in case of polyatomic molecules, containing more than two atoms in a molecule )
