Question

if x number of pentagonal rings and y number of hexagonal rings are present in buckminsterfullerene of Z carbon atom then
Ans= 5x-6y=2z

Answer 1

Answer:

5x - 6y = -2z or 6y-5x = 2z

Explanation:

Buckminsterfullerene is an allotrope of carbon which has a spherical (football like) structure containing 60 carbon atoms.

These 60 carbon atoms are arranged in form of 20 hexagonal rings and 12 pentagonal rings.

From the question, x = 12

                                y = 20

                                z = 60

5x - 6y = 5 x 12 - 6 x 20 = - 60

⇒ 5x - 6y = - 2z

Answer 2

Answer:

5x + 6y =3z

Explanation:

we know that there are 60 carbons in fullerene ,

which consist of 12 pentagonal rings and 20 hexagonal rings

comparing x=12 and y=20 we have z =60

now 5*12 + 6*20 = 3*60

       5x + 6y =3z
