The polymerization of 2,2-dimethyloxirane should be derived by anionic mechanism. Concept Introduction: Anionic polymerization: Initiator will be a nucleophile which reacts with the monomer to form a propagating site that is an anion and the initiator can be compounds like sodium amide or butyllithium. Nucleophile will attack on the alkene and the alkene contains a substituent that can withdraw electrons by resonance.

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.

Interpretation Introduction

Interpretation:

The polymerization of 2,2-dimethyloxirane should be described by cationic mechanism.

Concept Introduction:

Cationic polymerization: The polymerization in which an electrophile acts as an initiator and adds to the monomer which leads to the formation of a carbocation.

The initiator widely used is a Lewis acid and in the polymerization the electrophile adds to the sp2 carbon bonded to the most number of hydrogens.

3) Propagation of uncertainty. Every measurement has uncertainty. In this problem, we'll evaluate the uncertainty in every step of a titration of potassium hydrogen phthalate (a common acid used in titrations, abbreviated KHP, formula CsH5KO4) with NaOH of an unknown concentration. The calculation that ultimately needs to be carried out is: concentration NaOH 1000 x mass KHP × purity KHP molar mass KHP x volume NaOH Measurements: a) You use a balance to weigh 0.3992 g of KHP. The uncertainty is ±0.15 mg (0.00015 g). b) You use a buret to slowly add NaOH to the KHP until it reaches the endpoint. It takes 18.73 mL of NaOH. The uncertainty of the burst is 0.03 mL.. c) The manufacturer states the purity of KHP is 100%±0.05%. d) Even though we don't think much about them, molar masses have uncertainty as well. The uncertainty comes from the distribution of isotopes, rather than random measurement error. The uncertainty in the elements composing KHP are: a. Carbon: b. Hydrogen: ±0.0008…
