Which of the following is the carbon allotrope having a tetrahedral structure?
Diamond
In diamond, each carbon atom is sp3 hybridised and forms four equivalent covalent bonds directed toward the corners of a regular tetrahedron, generating a rigid three-dimensional network.
This uniform tetrahedral geometry (bond angle 109.5 degrees) explains diamond's exceptional hardness and high melting point.
Graphite is layered with sp2 carbons in planar hexagons; graphene is a single such planar sheet; fullerenes are closed spheroidal cages of sp2 carbon.
Hence, the tetrahedrally structured carbon allotrope is diamond.
