Question
Dipole-induced dipole interactions are present in which of the following pair?
-
H2O and alcohol
-
Cl2 and CCl4
-
HCl and He atoms
-
SiF4 and He atoms
Solution
C.
HCl and He atoms
Dipole-induced dipole interaction is present in the pair in which the first species is polar and the other is non-polar.
H2O and alcohol both are non-polar so there exist dipole-dipole interactions in between them.
Cl2 and CCl4 both are non-polar so there exists induced dipole -induced dipole interactions in between them. Similarly is true for SiCl4 and He atoms pair.
HCl is a polar molecule, whereas He atoms are non-polar, so in between them dipole-induced dipole interactions exist.
