QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Preparation and Properties of Carboxylic Acids.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12

Describe the effect of branching on the boiling point of carboxylic acids.
Describe the effect of electron-withdrawing groups on the acidity of carboxylic acids.
Describe the mechanism of esterification of carboxylic acids with alcohols.
Explain why benzoic acid is less acidic than formic acid.
Explain why carboxylic acids are more acidic than alcohols.
Explain why carboxylic acids have higher boiling points than alcohols of comparable molecular mass.
Explain why dicarboxylic acids are generally more acidic than monocarboxylic acids.
Explain why formic acid is a stronger acid than acetic acid.
Write the chemical equation for the preparation of acetic acid from methyl magnesium bromide (a Grignard reagent).
Write the equation for the hydrolysis of ethyl cyanide to form a carboxylic acid.
Write the IUPAC name of the carboxylic acid formed by the oxidation of ethanol.
A mixture of sodium benzoate and soda lime is heated. Write the chemical equation for the reaction and name the organic product formed.
A student attempts to prepare benzoic acid by oxidizing toluene with potassium permanganate under acidic conditions. Write the balanced chemical equation for this reaction and explain the role of the oxidizing agent.
