Yield and atom economy of chemical reactions (chemistry only)
Question
- A. formula and unit: (chemistry only) Define yield as the amount of product obtained from a reaction
- B. wrong formula: uses a different Unit 4.3 relationship from Percentage yield
- 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) Define yield as the amount of product obtained from a reaction.
Explanation
The correct option is formula and unit: (chemistry only) Define yield as the amount of product obtained from a reaction. It is correct because it directly supports the approved learning objective to (chemistry only) Define yield as the amount of product obtained from a reaction. This belongs to Percentage yield 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
Confusing Yield Definition
Students often confuse yield with the theoretical yield, thinking it refers to the maximum possible amount of product rather than the actual amount obtained.
Clarify that yield specifically refers to the actual amount of product obtained from a reaction, not the theoretical maximum.
