Polymers Flashcards
Why can polyamides and polyesters be hydrolysed but not polyalkenes?
- Polyesters and polyamides contain polar bonds but polyalkenes do not.
What is the general formula for an amino acid in acidic solution.
RC(NH3+)COOH
disadvantage of burning polymers
release carbon dioxide and other toxic gases
Why must a locating agent be used to identify amino acids using thin-layer chromatography?
Amino acids are often colourless.
What are the advantages that computer aided design brings to development of drugs targeting enzyme activity?
- accelerate the drug discovery process
- by stimulating interactions between drugs and enzymes
- predicting potential drugs
- optimising structure for enhanced efficacy and reduced side effects
Disadvantages of recycling polymers
- polymers have to be manually sorted
- this is a labour and energy-intensive process
what are the monomers that react to form polyamides
dicarboxylic acids and diamines
Why are addition polymers (polyalkenes) non-biodegradable?
they are non-polar and not susceptible to nucleophilic attack
what is an advantage of recycling polymers
they do not take up space in landfill
