    Dipole-induced dipole interactions are present in which of the following pairs?  [NEET 2013]

    A)  \[{{H}_{2}}O\] and alcohol

    B)      \[C{{l}_{2}}\] and \[CC{{l}_{4}}\]

    C)  \[HCl\] and \[He\] atoms

    D)  \[Si{{F}_{4}}\] 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:
