Worked Solution & Example Answer:Which statement about (CH₃)₂CHCH₂COOH is correct? A) In aqueous solution it reacts with magnesium to form carbon dioxide - AQA - A-Level Chemistry - Question 17 - 2021 - Paper 3
Step 1
B) It can form hydrogen bonds.
Answer
The compound (CH₃)₂CHCH₂COOH, which is 2-methylbutanoic acid, contains a carboxylic acid functional group (-COOH) that is capable of forming hydrogen bonds due to the presence of the highly electronegative oxygen atom. This ability to form hydrogen bonds significantly affects the compound's physical properties, such as its solubility in water and its boiling point.
