Carbon and silicon belong to group `IV`. The maximum coordination number of carbon in commonly occuring compounds is four whereas that of silicon is six. This is due to

A

Large size of silicon

B

More electropositive nature of silicon

C

Availability of low lying d-orbitals in silicon

D

Both (a) and (b)

Text Solution

Verified by Experts

The correct Answer is:
C
Carbon does not have d–orbitals but silicon has empty d–orbitals which can be used for 6 coordination number.
