Question
Graphite is thermodynamically the most stable allotrope of carbon at standard conditions. Which of the following factors best explains its excellent dry lubricating properties at high temperatures?
Answer: C
💡 Solution & Explanation
Graphite consists of 2D planar sheets of $sp^2$ hybridized carbon. These adjacent layers are separated by a large distance ($340 \text{ pm}$) and are held together only by weak van der Waals forces, allowing the planes to slide over each other easily.
