Question

Carbon shows a maximum covalency of four whereas other members can expand their covalence due to (A) absence of d-orbitals in carbon (B) ability of carbon to form pπ - pπ multiple bonds (C) small size of carbon (D) catenation of carbon

Tardigrade Admin · Accepted Answer

In carbon, due to absence of d-orbital, only s and p-orbitals are available for bonding, therefore, it can accommodate only four pairs of electrons around it. Thus, it has a maximum covalency of four.
