Answer 2

The correct option is (i).

• The species which contain a lone pair of electrons can donate its electrons and act as a lewis base while the species which have a deficiency of electrons can accept electrons and act as a lewis acid.
• Among the above compounds, aluminium trichloride has three strong electrons withdrawing Cl groups which attracts the electron density of Al and Al to become electron-deficient and act as a lewis acid.
