Question

Identify the functional groups present in each molecule.

A 19-carbon compound is composed of one five-membered ring and three six-membered rings.
Carbon 3 is double bonded to an oxygen and attached to carbon 2 and carbon 4.
Carbon 17 is attached to an oxygen, which is attached to a hydrogen.
i. hydroxyl group
ii. carboxyl group
iii. carbonyl group
A central carbon is attached to an amine, two hydrogens, and a carbon that is double bonded to an oxygen and single bonded to an oxygen attached to a hydrogen.
i. amino group
ii. carboxyl group
iii. amide group

Answer 1

Carbon 3 is double bonded to an oxygen and attached to carbon 2 and carbon 4. :

Answer: Carbonyl group ( Ketone or aldehyde)

Carbon 17 is attached to an oxygen, which is attached to a hydrogen. :

Answer: Carboxyl group (Carboxylic acid)

A central carbon is attached to an amine, two hydrogens, and a carbon that is double bonded to an oxygen and single bonded to an oxygen attached to a hydrogen. :

Answer: Amide group

An amide group contains both amine and carboxyl
