Question

Graphite is a soft lubricant yet it is extremely difficult to melt. What is the reason for this anomalous behavior?

• A. It has carbon atoms arranged in large plates of rings of strongly bound carbon atoms with weak interpolate bonds.
• B. It is a non-crystalline substance.
• C. It is an allotropic form of carbon.
• D. It has only single bonds between carbon atoms.

Answer 1

The correct option is A

It has carbon atoms arranged in large plates of rings of strongly bound carbon atoms with weak interpolate bonds.

Graphite is a soft lubricant yet it is extremely difficult to melt. The reason for this anomalous behavior is that graphite has carbon atoms arranged in large plates of rings of strongly bound carbon atoms with weak interpolate bonds.
