d-orbitals)
(2) BiCl5 (Bi5+ being an oxidizing
agent oxidizes Cl ion to Cl2 and Cl- ion being a reducing
agent reduces Bi5+ to Bi3+).

This may presumably be due to more
tendency of Bi to form three rather than five covalent bonds (inert pair
effect). Thus there are weak forces of attraction between their atoms in
solid state, accounting for its low m.p.
