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

Phenol is the starting material for the synthesis of 2,3,4,5,6-pentachlorophenol, known al-ternatively as pentachlorophenol, or more simply as penta. At one time, penta was widely used as a wood preservative for decks, siding, and outdoor wood furniture. Draw the structural formula for pentachlorophenol and describe its synthesis from phenol.

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.
