A fullerene with formula C₈₀ has x pentagons, y hexagons, z faces and w edges. The value of (w + z − y)/x is :-
Options:
Answer:
C
Solution:
Every fullerene has x = 12 pentagons. For C₈₀ : y = (80/2 − 10) = 30 hexagons, faces z = 42, edges w = 3 × 80/2 = 120 (Euler check : 80 − 120 + 42 = 2). (120 + 42 − 30)/12 = 132/12 = 11.
