Question

Consider a prototypical fullerene, $C_{60}.$
Let, a = number of 5-membred rings
b = number of 6-membered rings
c = number of $\pi$ bonds in $C_{60}$
Find the value of (3a – 2b + c). Report your answer after dividing it by 13.___

Answer 1

$a=12,b=20,c=30$

$3a-2b+c=26$

$\frac{26}{13}=2$
