why carbon do...

Question

why carbon does have a larger tendancy of catenation than silicon although they have same number of electrons?

Solution

Carbon differ from Si to form chains. This is possible due to high tendency of C to show catenation property which is more prominent in C than Si.
This is because the C-C bonds are very strong with high bond energy 348 kJ /mol while Si-Si bond is weak with lower bond energy 297 kJ /mol.
