Verified step by step guidance1
Begin by understanding the structure of abscisic acid, which is a plant hormone involved in various plant processes.
Identify the common functional groups found in organic molecules, such as hydroxyl (-OH), carbonyl (>C=O), amino (-NH2), and carboxyl (-COOH) groups.
Consider the chemical properties and roles of abscisic acid, which is known to be a weak acid. This suggests the presence of a functional group that can donate a proton (H+).
Recall that the carboxyl group (-COOH) is a common acidic functional group in organic acids, capable of donating a proton, which aligns with the acidic nature of abscisic acid.
Conclude that the carboxyl group is likely part of abscisic acid due to its ability to act as an acid, consistent with the hormone's properties.
