Question

Bond angle in structure of diamond is:

• A. ${109.5}^{o}C$
• B. ${210}^{o}C$
• C. ${200}^{o}C$
• D. ${154}^{o}C$

Answer 1

The correct option is A ${109.5}^{o}C$

Diamond is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centred 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 $1.544\times {10}^{-10}$ meter away with a $C-C-C$ bond angle of ${109.5}^0$.

Hence, the correct option is $A$
