Question 27
Which reagent reacts with ethanol and also reacts with ethanoic acid? A) acidified potassium dichromate(VI) B) sodium C) sodium carbonate D) sodium hydroxide
Worked Solution & Example Answer:Which reagent reacts with ethanol and also reacts with ethanoic acid? A) acidified potassium dichromate(VI) B) sodium C) sodium carbonate D) sodium hydroxide - CIE - A-Level Chemistry - Question 27 - 2012 - Paper 1
Step 1
Identify the reagents and their reactions with ethanol
Answer
Ethanol is an alcohol, and it generally reacts with oxidizing agents. Among the given options, only acidified potassium dichromate(VI) is a known oxidizing agent that can react with ethanol, converting it to an aldehyde and further to an acid under the right conditions.
Step 2
Identify the reagents and their reactions with ethanoic acid
Answer
Ethanoic acid (acetic acid) is a weak acid that can also react with strong oxidizing agents and bases. Acidified potassium dichromate(VI), while an oxidizer, can also react with ethanoic acid under certain conditions, leading to its oxidation.
