Which term is a group of five carbon atoms with one at the center?

• A. Surface Graining
• B. Tetrahedron
• C. Symmetry
• D. Thermal conductivity

Answer: (B)

A five-atom cluster with one atom at the center forms a tetrahedral arrangement: the central atom is bonded to four surrounding atoms that sit at the corners of a regular tetrahedron. This geometry is driven by sp3 hybridization, giving bond angles of about 109.5 degrees and producing the characteristic diamond-like network where each carbon connects to four neighbors. The other terms don’t describe a specific five-atom cluster: surface graining relates to surface texture, symmetry deals with invariance under operations, and thermal conductivity concerns heat transfer. So the term that captures this arrangement is tetrahedron.
