A pharmaceutical manufacturer is comparing two synthetic routes for the industrial production of a new cardiovascular medication. To determine the most efficient and sustainable process, the engineers have already calculated and compared the atom economy, the percentage yield, the toxicity of the solvents used, and the raw material costs.
State one other factor (not already molecularly or economically mentioned) that must be considered when selecting the preferred industrial pathway.
157 exam-style questions on Edexcel GCSE Chemistry 6.2 Quantitative analysis, covering 6.2.1 Concentration in mol dm⁻³ and titration calculations, 6.2.2 Percentage yield and why actual yield falls short, 6.2.3 Atom economy of a reaction, 6.2.4 Choosing a reaction pathway, and 6.2.5 Molar volume of gases and Avogadro's law. Each one has a worked solution and a mark scheme showing where the marks go.
