Question

Bond lengths which are present in diamond is:

• A. 234 pm
• B. 154 pm
• C. 900 pm
• D. 600 pm

Answer 1

The correct option is B 154 pm

Diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice.

In a diamond, the carbon atoms are arranged tetrahedrally.Each carbon atom is attached to four other carbon atoms $1.544\times {10}^{-10}=154.4$ pm meter away with a $C-C-C$ bond angle of ${109.5}^0$.

Correct answer is option-B.
