Amongst the following, the chromophore(s) is/are:
Show Hint
Chromophores are responsible for the absorption of light and the coloration of molecules. Common chromophores include the Azo, Anthraquinone, and Phthalocyanine groups.
Updated On: Apr 28, 2025
- Anthraquinone
- Azo
- Phthalocyanine
- Mono-chloro triazine
Hide Solution
Verified By Collegedunia
The Correct Option is A, B, C
Solution and Explanation
Step 1: Definition of a chromophore.
A chromophore is a part of a molecule responsible for its color, typically through the absorption of certain wavelengths of light.
Step 2: Identifying chromophores.
Anthraquinone is a common organic compound that absorbs visible light and imparts color, making it a chromophore.
Azo compounds contain a nitrogen-nitrogen double bond (\(N=N\)) that can absorb light and are well-known chromophores.
Phthalocyanine is a complex macrocycle with metal centers that also absorbs light, making it a chromophore.
Step 3: Conclusion. Therefore, the chromophores in the given options are Anthraquinone, Azo, and Phthalocyanine.
