The crystalline forms of carbon are diamond, graphite and ________.
Open in App
Solution
The correct option is D fullerene
There are three crystalline forms of carbon:
- Diamond
- Graphite
- Fullerene
Different forms, or allotropes, of carbon are diamond,
graphite, and fullerenes. In diamond, each carbon atom is bonded to four other
carbon atoms, forming a rigid structure that makes diamond very hard. In
graphite, each carbon atom is bonded to three other carbon atoms, and the atoms
forms layers that are only weakly bonded together. This makes graphite soft and
slippery. In a fullerene, carbon atoms are bonded to three other atoms in a
soccer ball pattern. The bonds are weak, so fullerenes can dissolve and form
solutions.
