Practise marking exact repeat units and recognising carbon-chain, ester, amide and oxygen linkages in addition and condensation polymer structures.
Concentrated ammonia solution gives off ammonia gas. Concentrated hydrochloric acid gives off hydrogen chloride gas. Ammonia, , and hydrogen chloride, HCl , are both colourless gases. Ammonia reacts with hydrogen chloride to make the white solid ammonium chloride.
Apparatus is set up as shown.
After ten minutes a white solid forms in the tube where the gases meet.
Nylon and proteins are both polymers containing nitrogen.
Name the linkages found in the polymers of nylon and protein.
