Open in App
Solution
The correct option is D Coke
The explanation for the correct option
- Solids that do not have definite geometrical forms are called amorphous solids or pseudo solids.
- Such solids are also known as micro-crystalline solids.
- In this type of solids, the particles are arranged in short-range order.
- Some common types of amorphous forms of Carbon are charcoal, lampblack, coke, and gas carbon.
The explanation for incorrect options -
Diamond, Fullerene, and Graphite are crystalline allotropes of carbon.
Hence, option D is the correct answer.
