polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.

Polymerization is one of those processes where 𝘀𝗺𝗮𝗹𝗹 𝗺𝗼𝗹𝗲𝗰𝘂𝗹𝗲𝘀 (𝗺𝗼𝗻𝗼𝗺𝗲𝗿𝘀) link together repeatedly to form very large molecules called polymers 🧬.


Examples of polymers include:

[1] Nylon

[2] Artificial rubber

[3] Plastics

[4] Polyethene

[5] Bakelite

Now let’s test the options.

A. Nylon and soap

Nylon → made by polymerization

Soap → made by saponification (reaction of fat with alkali)𝗺𝗮𝗱𝗲 𝗯𝘆 𝘀𝗮𝗽𝗼𝗻𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻 (𝗿𝗲𝗮𝗰𝘁𝗶𝗼𝗻 𝗼𝗳 𝗳𝗮𝘁 𝘄𝗶𝘁𝗵 𝗮𝗹𝗸𝗮𝗹𝗶), not polymerization.

B. Ethanoic acid, margarine and ethanol

These are small organic molecules made by other reactions like fermentation or esterification, not polymerization.

Nylon → polymer formed from 𝗱𝗶𝗮𝗺𝗶𝗻𝗲 𝗮𝗻𝗱 𝗱𝗶𝗰𝗮𝗿𝗯𝗼𝘅𝘆𝗹𝗶𝗰 𝗮𝗰𝗶𝗱.

Artificial rubber → polymer made from 𝗺𝗼𝗻𝗼𝗺𝗲𝗿𝘀 𝗹𝗶𝗸𝗲 𝗯𝘂𝘁𝗮𝗱𝗶𝗲𝗻𝗲.

Both are produced by polymerization.

D. Soap and butane

Soap → saponification

Butane → simple hydrocarbon from petroleum.

E. Margarine and nylon

Margarine is produced by 𝗵𝘆𝗱𝗿𝗼𝗴𝗲𝗻𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗼𝗶𝗹𝘀, not polymerization.
