Yield and atom economy of chemical reactions (chemistry only)

Question

A. formula and unit: (chemistry only) Explain why reactions with high atom economy are important for sustainable development
B. wrong formula: uses a different Unit 4.3 relationship from Atom economy
C. wrong unit: gives a value without checking the required unit
D. wrong reasoning: confuses coefficients, subscripts, mass, moles, or concentration

Answer

The correct option is formula and unit: (chemistry only) Explain why reactions with high atom economy are important for sustainable development.

Explanation

The correct option is formula and unit: (chemistry only) Explain why reactions with high atom economy are important for sustainable development. It is correct because it directly supports the approved learning objective to (chemistry only) Explain why reactions with high atom economy are important for sustainable development. This belongs to Atom economy within Yield and atom economy of chemical reactions (chemistry only), so the answer must use the named Unit 4.3 relationship and avoid mixing it with nearby ideas such as mass, moles, concentration, yield, atom economy, gas volume, coefficients, or subscripts.

Common mistake

Misunderstanding Atom Economy

Students often confuse atom economy with percentage yield, thinking they measure the same thing.

Remind students that atom economy focuses on the efficiency of starting materials turning into useful products, while percentage yield measures the actual product obtained compared to the theoretical maximum. Keep the correction anchored to Atom economy; check formula, substitution, calculation, final answer, and unit where relevant.
