Question

Diamond has a _______ structure while graphite has a ________ structure.

• A. tetrahedral, hexagonally layered
• B. pentagonal, hexagonally layered
• C. hexagonally layered, octahedral
• D. tetrahedral,square pyramidal

Answer 1

The correct option is A tetrahedral, hexagonally layered

Diamond has a tetrahedral structure as each C atom is bonded to four other C atoms.
Each C atom in graphite is bonded to three other C atoms forming a hexagonal layered structure. So graphite has a hexagonally layered structure.

Hence, the correct answer is Option (b).
