Question

Column I (Allotrope)	Column II (Property)
(A) White phopshporous	(P) Slippery layer structure
(B) Graphite	(Q) Covalently bonded 3D-Network like gaint structure
(C) Diamond	(R) Contain discrete molecules
(D) Fullerene	(S) $π$ -bonds in given allotropic form
	(T)Maximum 3σ-bonds by each atom

TestHub · Accepted Answer

(A) White Phosphorus: Consists of discrete P₄ molecules (R) where each phosphorus atom forms a maximum of 3 $σ$ -bonds .

(B) Graphite: Has a slippery layer structure (P) with sp² hybridized atoms forming $π$ -bonds (S) and 3 $σ$ -bonds .

(C) Diamond: A covalently bonded 3D-network giant structure (Q) where each carbon atom forms 4 $σ$ -bonds (thus, T is not applicable as it's not a maximum of 3).

(D) Fullerene: Consists of discrete C₆₀ molecules (R) with sp² hybridized atoms forming $π$ -bonds (S) and 3 $σ$ -bonds .
