Question

Which is not a characteristic property of carbon?

• A. Catenation
• B. Multiple bond formation
• C. Availability of d - orbitals for bonding
• D. Allotropy

Answer 1

Answer: (C)

Availability of d - orbitals for bonding

Configuration of carbon is $1s^{2}2s^{2}2p^2$. For $n=2$, there are no d orbitals. Also, carbon shows allotropy in form of graphite and diamond. Carbon is the best example of catenation and multiple bond formation.
