Carboxylic Acid Nomenclature
Q1: What is the IUPAC name for a four-carbon carboxylic acid?
A. Propanoic acid
B. Butanoic acid
C. Pentanoic acid
D. Butanal
Answer: B
Explanation: A four-carbon chain uses the prefix 'but-' and the suffix '-anoic acid' for carboxylic acids.
Esterification Reactions
Q2: The reaction between a carboxylic acid and an alcohol in the presence of an acid
catalyst is known as:
A. Saponification
B. Fischer Esterification
C. Hydrolysis
D. Oxidation
Answer: B
Explanation: Fischer esterification produces an ester and water from a carboxylic acid and alcohol.
Amine Basicity
Q3: Which of the following describes the nature of amines in aqueous solutions?
A. Strong acids
B. Weak acids
C. Weak bases
D. Neutral
Answer: C
Explanation: Amines are derivatives of ammonia and act as weak bases because the lone pair on the nitrogen can
accept a proton.

,Amide Formation
Q4: Amides are formed by the reaction of a carboxylic acid with which functional group?
A. Alcohol
B. Amine
C. Ether
D. Ketone
Answer: B
Explanation: The reaction between a carboxylic acid and an amine (or ammonia) forms an amide and water.
Physical Properties
Q5: Which compound would you expect to have the highest boiling point among those
with similar molar masses?
A. Ethane
B. Ethanol
C. Ethanoic acid
D. Dimethyl ether
Answer: C
Explanation: Carboxylic acids can form dimers via double hydrogen bonding, leading to significantly higher boiling
points than alcohols or alkanes.
