A structure of an organic compound is shown. Deduce the molecular formula of this compound.
Propanoic acid, $\text{C}_2\text{H}_5\text{COOH}$, reacts with methanol, $\text{CH}_3\text{OH}$, to make an ester. Name this ester and draw its structure, showing every atom and every bond.
State one application of esters.
Ethanoic acid may be made by the bacterial oxidation of ethanol. Give one other way of oxidising ethanol to produce ethanoic acid.
The simplified structures of a dicarboxylic acid monomer and a diamine monomer are shown. Draw the partial structure of the condensation polymer made from these two monomers so that two repeat units are shown, with every atom and every bond in the amide linkages included.
State what condensation means in condensation polymerisation.
Proteins contain amide linkages. When proteins are hydrolysed with dilute acid, name the type of compound formed.
