Select INCORRECT about the attractive forces operate between polar molecules & non polar molecules
Options:
Answer:
Solution:
The attractive forces between polar and non-polar molecules are primarily dipole-induced dipole forces (Debye forces) and London Dispersion Forces (LDFs).
A. The energy of dipole-induced dipole interaction is proportional to , where is the distance between molecules. This statement is correct.
B. Dispersion forces (LDFs) are always present between any two molecules, including polar and non-polar ones. Therefore, stating there is "no importance" of dispersion forces is incorrect. LDFs contribute to the overall attraction.
C. A larger non-polar molecule is more polarizable, leading to stronger induced dipoles and thus stronger dipole-induced dipole interactions. This statement is correct.
D. Xenon (non-polar) has some solubility in water (polar) due to dipole-induced dipole interactions and London Dispersion Forces. This statement is correct.
Therefore, the INCORRECT statement is B.
