Which of the following statements is false in the case of polar molecules?
- A Centres of positive and negative charges are separated in the absence of external electric field.
- B Centres of positive and negative charges are separated in the presence of external electric ficld.
- C Do not possess permanent dipole moments.
- D Ionic molecule \(\mathrm{HCl}\) is the example of polar molecule.
Answer & Solution
Correct Answer
(C) Do not possess permanent dipole moments.
Step-by-step Solution
Detailed explanation
Polar molecules are the molecules in which the centres of positive and negative charges are separated even there is no external field. Such molecules have a permanent dipole moment.
e.g., \(\mathrm{HCl}, \mathrm{H}_{2} \mathrm{O}\), etc.
Thus, statement given in option (c) is false.
e.g., \(\mathrm{HCl}, \mathrm{H}_{2} \mathrm{O}\), etc.
Thus, statement given in option (c) is false.
