Given below two statements: One is labelled as Assertion (A) and other is labelled as Reason (R).
Assertion (A): Non-polar materials do not have any permanent dipole moment.
Reason (R): When a non-polar material is placed in an electric field, the centre of the positive charge distribution of it’s individual atom or molecule coincides with the centre of the negative charge distribution.
In the light of above statements, choose the most appropriate answer from the options given below.
Assertion (A): Non-polar materials do not have any permanent dipole moment.
Reason (R): When a non-polar material is placed in an electric field, the centre of the positive charge distribution of it’s individual atom or molecule coincides with the centre of the negative charge distribution.
In the light of above statements, choose the most appropriate answer from the options given below.
View answer and explanation
Correct option: C
(A) is correct but (R) is not correct.
Option C ((A) is correct but (R) is not correct) is correct because while non-polar materials indeed lack permanent dipole moments, the reason provided is inaccurate; in an electric field, the charge distributions do not coincide, leading to induced polarization.
