Reactions of alkenes and alcohols (chemistry only)

Question

A. Ethanol
B. Methanol
C. Butanol
D. Propanol

Answer

The correct option is Ethanol.

Explanation

The correct option is Ethanol. Ethanol is correct because it directly supports the approved learning objective to know the conditions used for fermentation of sugar using yeast. This belongs to Alcohols within Reactions of alkenes and alcohols (chemistry only), so the answer must use the correct organic chemistry context. The other options are incorrect when they confuse the organic family, formula type, reaction condition, product, or property being tested. Keep molecular formula, structural formula, displayed formula, and general formula distinct. Do not confuse alkanes with alkenes, saturated with unsaturated, cracking with combustion, polymers with monomers, or hydrocarbons with oxygen-containing alcohols and carboxylic acids. When formulae are used, preserve the stored notation exactly and explain the GCSE chemistry idea in words rather than using unsupported displayed-formula diagrams.

Common mistake

Misunderstanding Fermentation Conditions

Students often confuse the conditions for fermentation with those for other processes, such as distillation or combustion.

Focus on the specific conditions for fermentation, which typically include a warm environment, the presence of yeast, and an anaerobic (absence of oxygen) setting.
