Explain why the preparation of Nylon- 6,10 occurs under milder conditions when decanedioyl dichloride is used instead of decanedioic acid.

Homework Answers

Answer #1

The monomers of nylon are-A six-carbon diamine (1 ,6-hexanediamine) and a ten-carbon dicarboxylic acid (decanedioic acid).the amine and carboxylate functional groups condense to form amide bonds only at relatively very high temperatures which is not possible in laboratory conditions. So, to make this reaction take place under very mild conditions in lab, a monomer with more reactive functional group than a carboxylic acid is preferred. Acyl chlorides are far more reactive than carboxylic acid, so diacyl chloride or (decanedioyl chloride) is used.

Most reactions that can be done under acidic conditions can also be done under basic conditions – for example, conversion of a ketone into a ketal. That said, the reason Fischer esterifications require acid catalysis is that protonating the acid makes the electrophile (the carbonyl carbon) a better electrophile. We could presumably make the nucleophile (an alcohol) a better nucleophile, which is usually done through deprotonation. Explain why reacting an alkoxide with a carboxylic acid will not result in a...
