An allotrope of carbon that exists as interconnected rings that assume a cylindrical shape is called
A) an octahedral.
B) a nanotube.
C) a diamond.
D) a fullerene.
E) graphite.

Question

Quizplus · Accepted Answer

The description matches that of a carbon nanotube, which is a cylindrical arrangement of carbon atoms in interconnected rings. A is incorrect as octahedral carbon is not cylindrical. C is incorrect as diamonds do not have a cylindrical shape. D is partially correct, as fullerenes are also made up of interconnected carbon rings, but they have different shapes (such as spherical or ellipsoidal) and are not cylindrical in shape. E is incorrect as graphite is made up of flat layers of interconnected carbon rings arranged in a planar structure.
