Question

Allotropes of carbon differ in the:

• A. Number of neutrons
• B. Physical states
• C. Way the atoms are arranged
• D. Number of proton

Answer 1

The correct option is C Way the atoms are arranged

Allotropy is the property of some elements to exits in two or more forms. The atoms of different form are bonded together in different manner.
Allotropy refers only to different forms of an element within the same physical state.
In diamond, carbon atoms are tetrahedrally bonded.
In graphite, atoms are bonded in hexagonal lattice.
In fullerene, the carbon atoms are bonded together in spherical, tubular, or ellipsoidal forms.
