1.	Give reasons for the following (a) `C Cl_(4)` is immiscible in water, whereas `SiCl_(4)` is easily hydrolysed. (b) Carbon has a strong tendency for catenation compared to silicon.
Answer» (i) `C Cl_(4)` is immicible with water and cannot be hydrolysed because the central carbon atom has no vacant orbitals and cannot accept elec tron pairs from `H_(2)O` molecules, On the other hand, `SiCl_(4)` can be easily hydrolysed because silicon atom has vacant 3d orbitals and can accept electron paris from `H_(2)O` molecuels.
