Question

Fluorine differs from the other halogens due to :

• A. Small size
• B. Very high electronegativity
• C. Non-availability of d-orbitals
• D. All of these

Answer 1

The correct option is D All of these

Fluorine differs from other halogens in many respects.
1. Smallest size of (F) atom
2. Highest ionization energy and electronegativity of fluorine than other halogens.
3. Fluorine cannot expand their octet beyond 8 because of lack of d-orbital, but other halogens can expand their octet.

Hence, the correct option is D.
