Practice objective / multiple choice question 26 from the 2018 Gce Model Questions Vol1 Chemistry examination.
A four‑step synthesis of compound X from cyclohexanone proceeds as follows: (i) oxime formation, (ii) Beckmann rearrangement, (iii) hydrolysis, (iv) decarboxylation. The isolated yields of steps (i), (ii) and (iv) are \(85\%\), \(78\%\) and \(70\%\) respectively. The overall isolated yield of X is \(30\%\). Calculate the isolated yield (as a percentage) of the hydrolysis step (iii) and state which step is the most inefficient.
