Thermosetting plastics have in general
- A. Molecular chains that slip past one
- B. Be a ceramic since all ceramics are glass and glass is a kind of ceramic
- C. Have a monolithic crystal structure
- D. Have no long range crystalline lattice structure
Answer: D. Have no long range crystalline lattice structure
Explanation: Thermosetting plastics are characterized by high melting points and the inability to be recycled once cured. They form cross-linked chain networks rather than long independent chains, which means they fundamentally lack any long-range crystalline lattice structure.
