The structure of butan-2-ol is shown on the side, black spheres represent carbon, grey spheres represent hydrogen and the red sphere represents oxygen.

The reaction of butan-2-ol with hot concentrated phosphoric(V) acid forms

A positive triiodomethane test (i.e. iodoform test) would produce a pale yellow precipitate (shown left) with an antisceptic smell.

The triiodomethane reaction can be used to distinguish between ethanol and propan-2-ol.

A chemist reacts a compound with neutral iron(III) chloride and obtains a violet solution (shown on the left). What can the chemist conclude about the compound?

Phosphorus pentachloride is a solid reagent (shown left) which can be used in the lab to test for the presence of an -OH group.

Ethene can be oxidised to an alcohol which reacts with phosphorus pentachloride to form

A chemist reacts phenol with bromine water. The orange brown colour of the bromine water is delcolourised and a white precipitate is formed. The white precipitate formed is

The structure of ethanal is shown on the left, black spheres represent carbon, grey spheres represent hydrogen and the red sphere represents oxygen.

Ethanol can be oxidised to ethanal by using appropriate reagents and conditions. This conversion can be carried out using

The structure of iodoethane is shown on the left, black spheres represent carbon, grey spheres represent hydrogen and the purple sphere represents iodine.
