Write the equation for the reaction of propan-1-ol with sodium metal.
Give the order of the relative acidities of propanoic acid, propan-1-ol and phenol, with the most acidic first.
Explain your answer to (i).
Methanoic acid, $\text{HCO}_2\text{H}$, has a similar acid strength to propanoic acid. Describe a chemical test that can distinguish between these two acids. Name the acid that gives a positive result in this test and describe the observations that would be seen.
The ester phenyl propanoate, $\text{C}_2\text{H}_5\text{CO}_2\text{C}_6\text{H}_5$, can be prepared from phenol and propanoic acid by a two-step synthesis. The first step produces an acyl chloride. For this two-step synthesis, • draw the structure of the product from the first step, • state the reagents and conditions required for each step of the synthesis.
Identify $Z$ from the proton NMR spectrum.
State one feature that would be seen, and explain why, in the proton NMR spectra of each of the two compounds that are not $Z$.
