Question

BlackTom AI · Accepted Answer

The question asks which option has a structure very different from the other three.
Option a: 'a. silica, SiO2' is a compound composed of silicon and oxygen linked in a network (SiO4 tetrahedra) and often forms materials like quartz. This represents a different type of structure (a network solid with both Si and O) compared to the purely elemental carbon or silicon frameworks.
Option b: 'b. silicon, Si' is an element that typically crystallizes in the diamond cubic structure, which is a strong, covalent network similar in nature to diamond rather than to graphite. Its structural motif is uniform and networked, but still within an elemental, covalent network category.
Option c: 'c. diamond, C' is another elemental covalent network where each carbon is tetrahedrally bonded to four others in a rigid 3D lattice. This is a classic network solid with a structure quite similar in bonding philosophy to silicon’s, though with carbon instead of silicon.
Option d: 'd. graphite, C' consists of carbon atoms arranged in layered, sp2-bonded sheets (graphene layers) held together by weaker van der Waals forces between layers. This is structurally distinct from the three others, which are all robust three-dimensional covalent networks (silicate network or diamond-like networks), whereas graphite has a layered, planar structure.
Putting it together, silica (SiO2) stands out most clearly as a compound with a network of Si–O bonds, differing in composition and bonding type from the elemental, covalent-network structures seen in silicon, diamond, and graphite.
