The mechanism for branching in free radical polymerisation of styrene is to be shown and the type of aliphatic hydrogen which is most likely to be abstracted is to be explained. Concept Introduction: Free radical polymerisation is the polymerisation in which polymer forms through free radical mechanism in which electrons are equally distributed between both atoms involved in bonding. Styrene polymerises via free radical polymerisation in the presence of benzoyl peroxide. To determine: The mechanism of the given reaction; also the type of hydrogen which is most likely to be abstracted in the given reaction.

Question

Correct each molecule in the drawing area below so that it has the condensed structure it would have if it were dissolv a 0.1 M aqueous solution of HCI. If there are no changes to be made, check the No changes box under the drawing area. No changes. HO—CH,—C—CH,—OH X 5 2 2 2 HO–CH,—CH,—C—CH,—OH Explanation Check Center Accessi ©2025 on 5 C

Answer 1

Question

Definition Definition Monomer units that are not only combined in the linear chain but are also attached through branches of different lengths along the main chain. Branched-chain polymers have a lower density, lower melting point, and lower tensile strength compared to linear chain polymers because branched-chain does not pack well. Examples of branched-chain polymers are amylopectin and glycogen.
