e. By what process does A transform to B? Sketch a plausible intermediate. [2 marks] f. A reacts cleanly with anhydrous HCl to release a gas and form compound C. Identify C, and explain why this is the sole product.
Salicylaldehyde reacts with diethyl zinc in a 1:1 ratio to form compound A according to the following scheme: OH O + Et Zn A + gas On cooling, compound B crystallises from solution, and half an equivalent of diethyl zinc is found to have reformed in solution. А B + 0.5 EtzZn
