(a(i))[1]
Write the equation for the reaction between $\text{C}_6\text{H}_5\text{OH}$ and Na.
(a(ii))[1]
Draw the structures of the two main isomeric organic products formed when phenol reacts with dilute $\text{HNO}_3$.
(b)[3]
Complete the mechanism in Fig. 9.3 for the reaction of $\text{C}_6\text{H}_5\text{O}^-$ with $\text{CO}_2$. Show all required curly arrows, dipoles and charges. Draw the structure of the organic intermediate.
(c(i))[1]
Draw three curly arrows in Fig. 9.4 to complete the mechanism for the Diels-Alder reaction between buta-1,3-diene and ethene.
(c(ii))[1]
Fig. 9.5 shows another Diels-Alder reaction of buta-1,3-diene. Predict the product formed in this reaction.
