The Functional Groups in Serotonin
Serotonin is a neurotransmitter that plays a crucial role in regulating mood, sleep, appetite, and other physiological processes. The correct option is -3200-3400, one sharp band. In terms of its functional groups, serotonin contains the following:
1. Amino Group: Serotonin has an amino group (-NH2) which is responsible for its classification as an amine. This functional group is involved in various chemical reactions and interactions within the body.
2. Hydroxyl Group: Serotonin also contains a hydroxyl group (-OH), which is an oxygen atom bonded to a hydrogen atom. This functional group is responsible for the presence of a sharp band in the infrared (IR) spectrum of serotonin, specifically in the range of -3200 to -3400 cm⁻¹.
Therefore, the correct answer is -3200-3400, one sharp band. This answer corresponds to the presence of the hydroxyl group in serotonin, which results in a sharp band in the IR spectrum within the specified range. It's important to note that the other options mentioned in the question do not accurately represent the functional groups present in serotonin.
