Reaction 3 takes place when is heated under reflux with acidified potassium dichromate(VI) solution.
State the colour change that takes place in the reaction mixture.
Construct an equation to represent reaction 3. Use [O] to represent an atom of oxygen from the oxidising agent.
Compound V is a liquid.
V contains 77.2 % carbon, 11.4 % hydrogen and 11.4 % oxygen by mass.
V has a relative molecular mass of 280 .
