The correct order of the increasing covalent character of the following is:

A$$SiCl_{4}\;<\;AlCl_{3}\;<\;CaCl_{3}\;<\;KCl$$
B$$KCl\;<\;CaCl_{2}\;<\;AlCl_{3}\;<\;SiCl_{4}$$
Correct Answer
C$$AlCl_{3}\;<\;CaCl_{2}\;<\;KCl\:<\:SiCl_{4}$$
Dnone of these

Solution

The correct order of the increasing covalent character is KClAs the electronegativity of the central atom increases, the attraction of the bond pair of electrons increases.
Hence, the covalent character increases.
