Question

explain various types of vander waal's force

Answer 1

Vanderwaal forces
Dipole-induced dipole
Induced dipole-induced dipole
Dipole dipole
Ion induced dipole

Strongest should be ion induced dipole

Answer 2

$\bigstar\large{\underline{\rm{\green{Types\:of\:Vander\:waal's\:forces:-}}}}$

★ Dipole-dipole interactions:-

→ Attraction between polar molecules. Positive of one molecule l attracted by negative pole of another.

Ex:- Attraction between HCl molecules.

★ Dipole-induced dipole interactions:-

→ Attraction between molecule having permanent dipole moment and a non polar molecule. Polar molecule induces polarity on non polar molecule.

Ex:- Noble gases get polarized in the presence of polar molecules.

★ Dispersion forces or London forces or induced dipole-induced dipole interactions:-

→ Attraction between non polar molecules. Polarity induced on the non polar molecules as electron of one attracts nucleus of another and repels electron cloud.

Ex:- Attraction between noble gases.
