Which type of intermolecular forces exist among the following molecule

1.	Which type of intermolecular forces exist among the following molecules?(i) H2S molecules (ii) H2O molecules (iii) Cl2 and CCl4 molecules (iv) SiH4 molecules (v) Helium atoms (vi) He atoms and HCl molecules.
Answer» (i) Dipole-dipole interactions (because H₂S is polar) (ii) Hydrogen bonding (iii) London dispersion force (because both are non-polar) (iv) London dispersion forces (because SiH₄ is non-polar) (v) London dispersion forces (because He atoms have symmetrical electron clouds) (vi) Dipole-induced dipole forces (because HCl is polar while He atom has symmetrical r electron cloud)
