An allotrophe of carbon having  a molecular mass of 720 is buckminsterfullerene.
Structure:
They are in the shape of soccer ball with 60 carbon atoms.
20 hexagons and 12 pentagons
They are called as bucky balls.
It is also the only pure form of molecular carbon utilized by our body.
Properties:
1.c60 is stable to withstand high temperature and pressure.
2.they stick together with Vander Waal forces.
3.The exposed surface of structure can selectively react with other species while maintaining the spherical geometry.
4. Atoms and molecules can be trapped within the moelcule without eacting.

Answer: An allotrope of carbon has a molecular mass of 720 is buckminsterfullerene. Buckminster Fullerenes are pure carbon's that are in the shape of spherical hollow cage like a soccer ball with 60 carbon atoms. They are called as 'Buckyballs' as their structure resembled a soccer ball.

Properties-:

C60 molecule is known for its symmetry

property. C60 molecule has three types of

rotation axes. 5-fold rotational symmetry is the

most common. It is through the centers of two

pentagons which are facing each other. 3-fold

rotation symmetry axes are from the central

point of 2-hexagonals which are facing each

other. At last, 2-fold symmetric axes are

through the edge centers of 2-hexagons. Hence

it is called the most symmetric molecule [11].

2-fold, 3-fold and 5-fold rotation symmetries

of C60
