Question

Dipole-dipole interactions are present in which of
the following pairs.
A.
Cl2 and CCl4
B.
HCl and He atoms
C.
HCl and H2S
D.
SiF4 and He atoms

Answer 1

Answer:

C. Will be correct answer

Explanation:

all others pair are not dipole pairs

Answer 2

Answer:

The correct answer is (B) HCl and He Atoms.

Explanation:

The forces or interactions, which occur between a polar molecule and a nonpolar molecule or with an atom are termed as Dipole -induced dipole interactions.

Here, HCl is polar while helium is non-polar; thus, it is an example of Dipole induced dipole.

In other options given:

(A) H2O and Alcohol are both polar.

(C) SiF4 and He atom are both non-polar.

(D) Cl2 and CCl4 are both non-polar molecules.
