Explain in detail.
(c) The proportion of covalent character in an ionic bond is decided by polarisability of the metal cation as well as the electronegativity of both elements involved in bonding. Polarisability is further decided by the density of positive charge on the metal cation. AICI3 is considered to show maximum covalent character among the given compounds. This is because Al 3 + bears 3 unit of positive charge and shows strong tendency to distort the electron cloud, thus the covalent character in Al-CI bond dramatically increases.
According to Fajans rule, cation with greater charge and smaller size favours covalency.
As the cation charge increases, covalent character also increases.
