Which of the following statements about intermolecular forces is(are) true?

London dispersion forces are the only type of intermolecular force that nonpnlar molecules exhibit.

Molecules that have only London dispersion forms will always be gases at room temperature ( 25  ° C ) .

The hydrogen-bonding forces in NH 3 are stronger than those in H 2 O .

The molecules in SO 2 ( g ) exhibit dipole-dipole intermolecular interactions.

CH 3 CH 2 CH 3 has stronger London dispersion forces than does CH 4 .

Interpretation Introduction



The given statements are true or false about intermolecular forces should be determined.

Concept Introduction:

Intermolecular forces are the force which is acting among molecules of a substance.


Reason for true statements:

Statement a) is true as in non polar molecule there is no other type of force present.

Statement d) is true statement as in sulphur dioxide there will be dipole −dipole interaction due to polar nature of sulphur dioxide molecule.

Statement e) is a true statement as propane has more London forces as compared to methane due to having more surface area of propane as compared to methane.

Statements a, d and e are true statements. In non polar molecule there is only chance to generate induced dipole which can induce another dipole...
