Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) F₂ > Cl₂ > Br₂ > I₂ (Wrong)

Actually, F–F bond is weaker than Cl–Cl due to strong lone pair repulsion in F₂.

Correct trend: Cl₂ > Br₂ > F₂ > I₂

(B) C–C < C=C < C≡C (Correct)

Bond strength increases with bond order (single < double < triple).

(C) C–C > Si–Si (Correct)

Carbon forms stronger bonds than silicon due to better overlap (smaller size).

(D) N–N < P–P (Correct)

N–N bond is weaker due to strong lone pair repulsion in small N atoms, while P–P is stronger.
