Chemistry - Complete Pblock- Question with Solution | TestHub

Explain the question: Pick correct statements on C-allotropes.

Concept: This question is based on structures of graphite, diamond, fullerene solution. Solution:

Graphite is the most stable allotrope and has 2-D hexagonal sp² layers → (1) true.

Diamond is hardest, with 3-D sp³ network → (2) true.

Fullerene C₆₀ is a recently discovered molecular allotrope, football-shaped → (3)

true.

Graphite layers are held by weak van der Waals forces, spacing ≈ 3.35 Å, not 6.14 Å

→ (4) false
