Hydroxy compounds — practice question

Phenol, $\text{C}_6\text{H}_5\text{OH}$, acts as a weak acid.
(a)[2]

Phenol can be prepared from phenylamine, $\text{C}_6\text{H}_5\text{NH}_2$. State the reagents and conditions for this reaction.

(b)[2]

Phenol reacts with dilute aqueous nitric acid at room temperature to produce a mixture of two isomeric compounds with molecular formula $\text{C}_6\text{H}_5\text{NO}_3$. Use the Data Booklet to sketch the structural formulae of these two products in the boxes and label each one.

(c(i))[2]

Phenol reacts with excess aqueous bromine. Draw and name the organic product of this reaction in the box.

(c(ii))[1]

Describe two visible observations that occur when phenol reacts with an excess of aqueous bromine.

(d)[1]

Write an equation for a neutralisation reaction in which phenol acts as an acid.

(e)[3]

Water, phenol and ethanol can all act as acids. Put these three compounds in order of acidity, starting with the most acidic. Explain your answer.
