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

  • H2O and alcohol

  • Cl2 and CCl4

  • HCl and He atoms

  • SiF4 and He atoms


C.

HCl and He atoms

Dipole-induced dipole interaction are present in the pair in which the first species is polar and the other is non-polar.H2O and alcohol both are polar molecules, so there exists dipole-dipole interactions in between them. Cl2 and CCl4 both are non-polar so there exists induced dipole-induced dipole interactions in between them. Similar 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.

The bond angle in NF3 (102.3°) is, smaller than NH3 (107.2°). This is because of

  • large size of F compared to H

  • large size of N compared to F

  • opposite polarity of N in the two molecules

  • small size of H compared to N
