Which type of intermolecular forces exist among the following molecule

1.	Which type of intermolecular forces exist among the following molecules ? (i) H_(2)S molecules (ii) H_(2)O molecules (iii) CL_(2) and C Cl_(4) molecules (iv) SiH_(4) molecules (v) Helium atomms (vi) He atoms HCl molecules
Answer» Solution :(i) Dipole-dipole interactions (because `H_(2)S` is POLAR). (II) Hydrogen bonding. (iii) London DISPERSION forces (becausearenon-polar). (iv) London dispersion forces (because `SiH_(4)` 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 electron cloud).
