Question

Celluloid is:
A.A thermoplastic material obtained from caprolactam and urea
B.A thermoplastic material obtained from cellulose nitrate and camphor
C.A thermosetting material obtained from urea and formaldehyde
D.A thermosetting material obtained from glycerol and formaldehyde

Answer 1

Hint: To solve this question, we must first understand the meaning of thermoplastic and thermosetting materials. Then on the basis of the molecular structure of celluloid, we can try to determine the compounds it is formed from, to get the correct answer.

Complete step by step answer:
Before we move forward with the solution of the given question, let us first understand some important basic concepts.
Thermoplastic materials: Thermoplastic materials can be identified as materials which can be reheated to modify the physical geometry or the shape of the material. Thermoplastics are usually highly reusable because of this property of theirs. Also, this heating does not cause any variation in their chemical or mechanical properties
Thermosetting materials: Thermosetting materials are the exact opposite of thermoplastic materials. Thermosetting materials cannot be reheated because they decompose upon heating. Hence, the recyclability of this material is very difficult.
Celluloid is one of the first plastics to ever be discovered. It also decomposes when heated. Hence, we can identify celluloid as a thermoplastic material. Celluloid is highly flammable and can damage other plastics as well. Compounds like nitrocellulose and camphor are used to prepare this material.
Hence, we can say that celluloid is A thermoplastic material obtained from cellulose nitrate and camphor.

Hence, Option B is the correct option

Note: Starting during the 1880s celluloid gained one of its most noticeable uses as a substitute for material in separable collars and sleeves for men's garments. Throughout the long term various contending plastics were presented under such whimsical names as Coraline, Ivoried, and Praline, and celluloid turned into a conventional term.
