Chapter 30, Problem 30.59P

Although chain branching in radical polymerizations can occur by intermolecular Habstraction as shown in Mechanism 30.2, chain branching can also occur by intramolecularH abstraction to form branched polyethylene that contains butyl groups asbranches.

Chapter 30, Problem 30.59P, 30.59 Although chain branching in radical polymerizations can occur by intermolecular H abstraction

a. Draw a stepwise mechanism that illustrates which H must be intramolecularly abstracted to form butyl substituents.

b. Suggest a reason why the abstraction of this H is more facile than the abstraction of other H’s.

Styrene derivatives such as A can be polymerized by way of cationic rather than radical intermediates. Cationic polymerization is an example of electrophilic addition to an alkene involving carbocations. a.) Draw a short segment of the polymer formed by the polymerization ofA.b.) Why does A react faster than styrene (C6H5CH=CH2) in a cationicpolymerization?
Which of the following molecules can be used as a monomer to generate this polymer? So the answer's B... im having quite the trouble understanding where in the polymer the double bond broke. Could someone explain and draw in EXTREME details how the answer's B and not any other answer choice?
Neat hand written explanation
