Directions : For the Assertion (A) and Reason (R) below, choose the correct alternative

Assertion(A) : Graphite is slippery and used as a lubricant.

Reason (R) : Graphite has free electrons.

C) A is true but R is false.	D) A is false but R is true.

Answer & Explanation Answer: B) Both A and R are true but R is NOT the correct explanation of A.

Explanation:

In graphite, each carbon atom is linked to three other carbon atoms while one electron in the carbon atom is delocalised. So, graphite has free electrons
