Question

Why is graphite used as a dry lubricant in machinery?

• A. Each carbon atom undergoes $s{p}^3$ hybridization in graphite
• B. Graphite has layered structure and its cleaves easily between the layers and therefore it is very soft and slippery
• C. Graphite is a non-conductor of electricity
• D. Graphite has two sigma bonds and two pi bonds

Answer 1

Answer: (B)

Graphite has layered structure and its cleaves easily between the layers and therefore it is very soft and slippery

Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant.

Answer: Graphite has a layered structure and its cleaves easily between the layers and therefore it is very soft and slippery.
