Find out all the functional groups present in the following polyfunctional compound.
Dopamine a neurotransmitter that is deficient in Parkinson's disease.
उत्तर
Functional groups: Phenolic –OH group (Ar–OH) and primary amine (-NH2) group are present in dopamine.
Explanation:
- Hydroxyl groups (-OH): Two hydroxyl groups are attached to the benzene ring.
- Amine group (-NH2): Although not explicitly shown in the given structure, dopamine has an amine group attached to the carbon chain extending from the benzene ring. This group would be attached to the end of the three-carbon chain (on the left end of the structure).
