Question
Which of the following functional groups is NOT found on the protonated G-acid?A) AlcoholB) BenzeneC) SulfonateD) Sulfite
Solution
To answer this question, we first need to understand what a G-acid is. G-acid, also known as Gamma acid, is a naphthol sulfonic acid used in the production of dyes.
The functional groups present in G-acid are:
- Alcohol: This is present as a hydroxyl (-OH) group attached to the benzene ring.
- Benzene: The basic structure of G-acid includes a benzene ring.
- Sulfonate: This is present as a sulfonic acid (-SO3H) group attached to the benzene ring.
However, G-acid does not contain:
- Sulfite: This is a different functional group (-SO3^2-) and is not present in G-acid.
So, the answer is D) Sulfite. This functional group is not found on the protonated G-acid.
