Dipole-induced dipole interactions are present in which of the following pairs?
Options
- AH ₂ O and alcohol
- BCl ₂ and CCl ₄
- CHCl and He atoms
- DSiF ₄ and He atoms
Correct answer
C. HCl and He atoms
Step-by-step solution
Dipole-induced dipole interaction are present in the pair in which the first species is polar and the other is non-polar. H ₂ O and alcohol both are polar molecules, so there exists dipole-dipole interactions in between them. Cl ₂ and CCl ₄ both are non-polar so there exists induced dipole-induced dipole interactions in between them. Similar is true for SiCl ₄ and He atoms pair. HCl is a polar molecule, whereas He atoms are non-polar, so in between them dipole-induced dipole interactions exist :
