A) \[{{\text{H}}_{\text{2}}}\text{O}\] and alcohol
B) \[\text{C}{{\text{l}}_{\text{2}}}\] and \[\text{CC}{{\text{l}}_{4}}\]
C) \[\text{HCl}\] and He atoms
D) \[\text{Si}{{\text{F}}_{4}}\] and He atoms
Correct Answer: C
Solution :
Dipole-induced dipole interaction are present in the pair in which the first species is polar and the other is non-polar. \[{{\text{H}}_{\text{2}}}\text{O}\] and alcohol both are polar molecules, so there exists dipole-dipole interactions in between them. \[\text{C}{{\text{l}}_{\text{2}}}\] and \[\text{CC}{{\text{l}}_{4}}\] both are non-polar so there exists induced dipole-induced dipole interactions in between them. Similar is true For \[\text{SiC}{{\text{l}}_{4}}\] and He atoms pair. HCI is a polar molecule, whereas He atoms are non-polar, so in between them dipole-induced dipole interactions exist:
