Options

  1. Aattracted by other molecules in the sphere of influence.
  2. Battracted by other molecules outside sphere of influence.
  3. Crepelled by other molecules outside the sphere of influence.
  4. Drepelled by other molecules in the sphere of influence.

Correct answer

A. attracted by other molecules in the sphere of influence.

Step-by-step solution

The sphere of influence is an imaginary sphere drawn with a molecule as its centre and the intermolecular range as its radius. The intermolecular force is attractive in nature for the molecules within this range. Therefore, the liquid molecule at the centre of the sphere of influence is attracted by other molecules present inside the sphere of influence. Molecules outside the sphere of influence are at a distance greater than the intermolecular range, so they do not exert any significant force on the central molecu
