Malachite Green is given as an example of which chemical class of dyes?
Correct answer: C. Triarylmethane dyes
- A. Azo dyes
- B. Anthraquinone dyes
- C. Triarylmethane dyes
- D. Nitro dyes
Explanation
Malachite Green belongs to the triarylmethane class of dyes. These dyes are recognized by their structure consisting of three aryl groups attached to a central carbon atom. In contrast, azo dyes have azo groups, anthraquinone dyes are based on the anthraquinone molecule, and nitro dyes contain nitro groups. Therefore, the correct answer is triarylmethane dyes.
