Nitrogen does not show pentacovalency because of:
- A. absence of s-orbitals
- B. absence of d-orbitals
- C. its small size
- D. none of these
Step-by-step solution
Nitrogen is in the second period and has only s and p orbitals in its valence shell. Pentacovalency would require five covalent bonds, which typically requires the use of d-orbitals (e.g., sp³d hybridization) to accommodate more than four bonds. Since nitrogen lacks d-orbitals, it cannot expand its octet and does not show pentacovalency.
