1.	Give a comparative account of the chemistry of carbon and silicon with regard to their (i) property of catenation and (ii) stability of hybrids and oxides.
Answer» (i) Carbon shows property of catenation to more extent than silicon due to small size and tendency to form pπ-pπ multiple bonds with itself (ii) Stability of hybrids: CH₄ is more stable than SiH₄ due to small size of ‘C’. (iii) CO₄ is gas whereas SiO₂ is three dimensional covalent solid, therefore highly stable as compared to CO₂.

(i) Carbon shows property of catenation to more extent than silicon due to small size and tendency to form pπ-pπ multiple bonds with itself

(ii) Stability of hybrids: CH₄ is more stable than SiH₄ due to small size of ‘C’.

(iii) CO₄ is gas whereas SiO₂ is three dimensional covalent solid, therefore highly stable as compared to CO₂.
