Interpretation Introduction

Interpretation:

The reason for the spherical shape of oil in water is to be determined.

Concept introduction:

The various kinds of interactions that bind a molecule are known as intermolecular forces. These can be forces of dispersion, dipole–dipole, ion–dipole, and hydrogen bonding.

Dispersion forces present in every molecule due to the presence of electron.

Dipole–dipole is the attractive force between opposite end of polar molecule.

Hydrogen bonding is the attractive force between hydrogen attached to an electronegative atom of one molecule and an electronegative atom of different molecule.

Ion–dipole force is the attractive force that due to electrostatic attraction between an ion and a neutral molecule.

The phenomenon by which a liquid tends to minimize its surface area is called surface tension.

The cause for surface tension is intermolecular forces. An example of this phenomenon is a drop of water or soap bubble.
