(a) Name the type of intermolecular forces existing in the molecules of `BCl_(3),NCl_(3)` and `NHCl_(2)`. (b) Which of these is most likely to exist in the condensed state and which one is least likely? |
|
Answer» (a) `BCl_(3)`, being symmetrical molecule has London forces only. `NCl_(3)`,being pyraimdal has a net dipole moment, i.e, it is polar and hence dipole-dipole forces are present in addition to London forces. `NHCl_(2)` has hydrogen bonding becauseof the presence of N-H bond in addition to London forces. (b) Due to presence of hydrogen bonding which is a strong bond compared to dipole-dipole and London forces, `NHCl_(2)` is most likely to be in comdensed phase. `BCl_(3)` has weakest intermolecular forces and hence is least likely to be in condensed phase, i.e., it is likely to be gaseous. |
