You would predict that indoleacetic acid, a plant hormone, would have a(n) carboxyl group.
The auxin group of naturally occurring plant hormones most frequently found is indole-3-acetic acid. It would be the most well-known auxin as well as the focus of in-depth research by plant physiologists. IAA would be an indole derivative with a carboxymethyl substituent.
The primary auxin in plants contains IAA, which controls a variety of growth and development activities including cell division elongation, tissue differentiation, apical dominance, as well as reactions to pathogens, light, including gravity.
Therefore, indoleacetic acid, a plant hormone, would have a(n) carboxyl group.
