Question

The number of pentagons in C₆₀ and trigons (triangles) in white phosphorus, respectively, are:

विकल्प

• 12 and 3

• 20 and 3

• 20 and 4

• 12 and 4

Answer 1

12 and 4

Explanation:

The C₆₀ molecule contains 12 pentagons in its structure. White phosphorus consists of P₄ tetrahedral molecules, where each P₄ molecule has 4 triangular faces (trigons). Therefore, the number of pentagons in C₆₀ is 12, and the number of trigons (triangular faces) in white phosphorus is 4
