Q. 35 B4.4( 9 Votes )

Explain why, graphit

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 4. Carbon and Its Compounds

Answer :

In graphite, each carbon atom is bonded with 3 other carbon atoms to form hexagonal rings which join together by weak Vander Waal forces to form layers. Due to the weak force, these layers can slide over each other and therefore, graphite can be used as a lubricant. Whereas diamond being extremely hard cannot be used as a lubricant.
