Question

consider the following diagram of a chemical reaction. initiation r - o - o - r heat 2 r - o• r - o• + h2c = c → h2c - c• ro ro what is the product that is formed in this reaction? a polymer a monomer an alkyl halide a carboxylic acid

Explanation:

Step1: Analyze reaction mechanism

The reaction starts with the homolytic cleavage of a peroxide ($R - O - O - R$) under heat to form alkoxy radicals ($R - O\cdot$). These radicals then add to the double - bond of the styrene - like monomer ($H_2C = CPh$) and propagate the chain by adding more monomers.

Step2: Identify product type

This is a free - radical polymerization reaction. In free - radical polymerization, monomers react to form long - chain polymers.

Answer:

A. a polymer
