Question

Which of the following statements is not correct regarding diamond and graphite?

• A. In diamond, each carbon atom is covalently bonded to three other carbon atoms.
• B. In graphite, each carbon atom is covalently bonded to three other carbon atoms in the same plane.
• C. The C-C bond length in graphite is intermediate between single an double bond distance.
• D. Diamond is a layered structure, the two layers joined by van der waals' forces.

Answer 1

Answer: (D)

Diamond is a layered structure, the two layers joined by van der waals' forces.

Structure of Diamond

Diamond has a three-dimensional rigid structure. In this, each carbon atom shares its electrons with four other carbon atoms forming four covalent bonds.

Hence, option "D" is the correct answer.
