(a)[3]
State the names of three functional groups present in the noradrenaline molecule.
(b(i))[2]
A two-stage synthesis of noradrenaline begins with dihydroxybenzaldehyde. In the box, draw the structure of the intermediate $Z$.
(b(ii))[2]
Suggest reagents for steps 1 and 2.
(c(i))[4]
Draw the structures of the products formed when noradrenaline is reacted with dilute $\text{NaOH(aq)}$.
(c(ii))
Draw the structures of the products formed when noradrenaline is reacted with dilute $\text{HCl(aq)}$.
(c(iii))
Draw the structures of the products formed when noradrenaline is reacted with an excess of ethanoyl chloride, $\text{CH}_3\text{COCl}$.
(d)[2]
Name the functional groups newly formed in the reaction in (c)(iii).
