Detailed Solution

The given statement is true.
Concept: An allotrope of carbon is graphite. The hexagonal arrangement of the carbon atoms gives it shape. Each carbon atom is covalently joined to three more carbon atoms, leaving one free delocalized electron.
Graphite is an important crystalline allotrope of carbon and it is found to have a slippery surface. In graphite, the ‘

C

’ atoms are arranged in a hexagonal structure and each carbon atom is connected to three other carbon atoms.
In graphite, each carbon is linked to three other carbon atoms hence leaving behind a free electron. Due to the occurrence of this one delocalised electron, graphite is a good conductor of electricity. Hence, the given statement is true.
Hence, the correct answer is option 1.
