To draw the structure of butyl rubber which is formed by the polymerization of isoprene and isobutylene in the presence of cationic initiator. Concept introduction: Cationic polymerization is the type of polymerization in which the cationic initiator transfers the charge to the monomer unit which then becomes reactive to proceed for further reaction. This reactive monomer further reacts to the same or other monomer to give the final product as polymer . Reactivity of monomer towards the cationic polymerization increases as the stability of the carbocation intermediate formed increases. Some examples of initiator used are: HClO 4 , H 2 SO 4 , CFCOOH etc., in all these initiators H + acts as an cationic initiator which starts the polymeric reaction. Here the butyl rubber formed is a copolymer because it has two different monomer units.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

A certain half-reaction has a standard reduction potential Ered +1.26 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 1.10 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box.. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box. yes, there is a minimum. 1 red Πν no minimum Oyes, there is a maximum. 0 E red Dv By using the information in the ALEKS…
