Worked Solution & Example Answer:Which statement about (CH₃)₂CHCH₂COOH is correct? A - AQA - A-Level Chemistry - Question 17 - 2021 - Paper 3
Step 1
B. It can form hydrogen bonds.
Answer
This statement is correct because the carboxylic acid group (-COOH) present in (CH₃)₂CHCH₂COOH is capable of forming hydrogen bonds with water or other polar molecules due to the electronegative oxygen atom, which attracts hydrogen atoms from other molecules. This hydrogen bonding can lead to increased solubility in water.
