Solution
Correct Answer:
All of these
Boron (B) exhibits anomalous behavior compared to Al,Ga,In,Tl due to its exceptionally small size.
- Properties:
- Non-metallic: Boron is a metalloid/non-metal, while all other group members are metals.
- Covalent Bonding: Due to its high ionization energy and small size, it does not form B3+ ions readily and forms covalent bonds.
- Octet Rule: Boron lacks d-orbitals in its valence shell (max covalency is 4). It cannot expand its octet to match the coordination numbers (6 or more) seen in heavier members like [AlF6]3−.
This easy difficulty chemistry question is from the chapter p-block elements, covering the topic of group 13 - boron family. It appeared in the 2025 exam.
