Practise MYP Chemistry questions on 6.2 Structural Formulae – Carboxylic Acids and Esters and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
In a molecule, as the length of the non-polar hydrocarbon chain attached to an ester functional group increases, the solubility of the ester in water __________.
The esterification reaction between a carboxylic acid and an alcohol is typically catalyzed by __________.
What is the name of the ester formed when methanol reacts with propanoic acid in the presence of an acid catalyst?
Which set of reactants would produce the ester ethyl propanoate?
True or False: Esters are highly soluble in water because they can donate hydrogen bonds to water molecules using their alkyl chains.
