Dipole-induced dipole interaction are present in which of the following pairs

Options

A. `Cl_(2)` and `C Cl_(4)`
B. `HCl` and `He` atoms
C. `SiF_(4)` and `He` atoms
D. `H_(2)O` and alcohole

Answer

B

Explanation

Dipole-induced dipole interactions are present in the pair in which the first species is polar and the other is non-polar. Both `CL_(2)` and `C CL_(4)` are non-polar so there exists induced dipole-induced dipole interaction in between them.
The same is true for `SiF_(4)` and `He` atoms pair.
In `H_(2)O` and alcohol, both are polar molecule, so there exists dipole-dipole interaction in between them.
`HCl` is a polar molecule, whereas `He` atoms are non-polar so in between them dipole-induced dipole interactions exist.
