Question

Three dimensional molecules with cross links are formed in the case of a:

• A. thermoplastic
• B. thermosetting plastic
• C. both $A$ & $B$
• D. None of the above

Answer 1

The correct option is B thermosetting plastic

Three-dimensional molecules with cross-links are formed in the case of a thermosetting plastic. These do not become soft on heating under pressure. Hence, cannot be remoulded and recycled. They cannot be reused. E.g Bakelite.

Hence, option B is correct.
