Question

In graphite the C - C bond length with in the layer is X pm and the distance between two adjacent layers is Y pm. X and Y respectively are

• A. 340, 141.5
• B. 141.5, 340
• C. 141.5, 154
• D. 143.5, 340 \bigskip

Hint:

Graphite facts: \[ \text{C-C bond length} = 141.5\,pm \] \[ \text{Interlayer distance} = 340\,pm \] Weak interlayer forces are responsible for the lubricating property of graphite.

Answer 1

The Correct Option is B
