help me please **Polystyrene Formation from Styrene: Mechanism and Explanation****Objective:**To understand the mechanism for the formation of polystyrene from styrene monomers, including key reaction steps such as initiation, propagation, and termination.**Process Overview:**1. **Starting Material:** - **Styrene**: It is the monomer used in the polymerization process. The chemical structure is represented by a vinyl group (C=C) attached to a phenyl group (Ph = C6H5).2. **Initiation:** - Utilizes an initiator (such as ROOR) and heat. This decomposes to form radicals that start the polymerization. - The radical (RO•) reacts with a styrene monomer, forming an activated styrene radical.3. **Propagation:** - The activated styrene radical reacts with another styrene monomer, creating a growing polymer chain with a radical at the end. - This step continues with the addition of multiple styrene units, lengthening the polymer chain.4. **Termination:** - Can occur through various mechanisms including combination or disproportionation of radical ends resulting in a final polystyrene chain without any reactive ends.**Polymer Structure:**- The repeating unit is polystyrene represented as: -[CH2-CH(Ph)]n-.- Here, [CH2-CH(Ph)] represents the backbone of the polystyrene, where Ph (C6H5) is the phenyl group attached to every other carbon atom.**Diagram Explanation:**- The diagram presents the transformation starting with a styrene molecule. The arrow direction indicates reaction progression leading to the formation of polystyrene.- A polymer chain segment is shown with repeating units displayed, each bearing a phenyl group (Ph) attached to the second carbon of the vinyl group.- The polymer chain is bracketed with an 'n' subscript denoting the number of repeating units, indicating the formation of a long polystyrene chain.Understanding and utilizing this mechanism allows the synthesis of polystyrene with varying molecular weights, crucial for applications in packaging, insulation, and consumer goods.

Polymerization is a reaction in which a monomer unit is used as a starting compound and it reacts with another monomer unit to form a polymer.The monomer is the building block of the polymer.In this reaction, the monomer is styrene, and more styrene reacts and forms polystyrene.The polymerization reaction of polysterene includes three steps:(1) Initiation(2) Prapagation (3) Termination
