Neco 2021 Chemistry Question 5
Practice objective / multiple choice question 5 from the 2021 Neco Chemistry examination.
Starting with 5.00 g of cyclohexanone, a three‑step synthesis is carried out: (i) reduction with NaBH₄ to cyclohexanol, (ii) oxidation with Jones reagent to cyclohexanecarboxylic acid, and (iii) esterification with methanol to give methyl cyclohexanecarboxylate. Assuming an overall yield of 85% for the three steps combined, calculate the mass of methyl cyclohexanecarboxylate obtained. Molar masses: cyclohexanone 100.16 g·mol⁻¹, cyclohexanol 100.16 g·mol⁻¹, cyclohexanecarboxylic acid 114.14 g·mol⁻¹, methyl cyclohexanecarboxylate 128.16 g·mol⁻¹.
