Question 6
HThe diagram gives a simplified oxidation scheme. The symbol [O] represents oxygen supplied by an oxidising agent; the scheme does not show balanced coefficients or water. For a new reaction, take R=C2H5\mathrm{R=C_2H_5}R=C2H5 rather than the example named beneath the scheme.
a.[4]
Deduce the name and condensed structural formula of the starting alcohol and of the carboxylic acid produced in this new reaction.
b.[2]
Write a balanced equation for this oxidation using [O] and including water.
c.[2]
Separate samples of the alcohol and the acid are added to sodium carbonate solution. Predict the observations and explain how the results distinguish the functional groups.
