NSAA Chemistry help
Alpha-linolenic acid is a polyunsaturated straight-chain carboxylic acid.
0.001 mol of the acid reacts exactly with 15 cm3
of 0.2 mol dm–3 aqueous bromine.
Alpha-linolenic acid contains 18 carbon atoms per molecule.
Which of the following is a formula for the acid?
Edit: I figured it out when writing the question, in short the molecule has 3 db bonds so its formula would be CnH2n-4, however since it's a carboxylic acid, the end carbon has not CH3 but COOH which means it's lost a further 2 hydrogen atoms.
