The structural formula for the carbanion formed by addition of hydroxide ion to methyl-2-cyanoacrylate is to be drawn. This structural formula has to be accompanied by a contributing resonance structure that shows delocalization of the negative charge to oxygen, and another to nitrogen. Concept introduction: A way of describing the delocalized electrons present in certain molecules is termed as resonance. The bonding in these cases cannot be expressed by a single Lewis structure. Efficient termination processes are absent in living polymerizations. These processes are terminated by the addition of substances which react with carbanions. For example: carbon dioxide or alcohol. In methyl-2-cyanoacrylate, a carbonyl group and a cyano group is attached to the same carbon.

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.
