Question

Chromophores consists of ________ which are responsible for color.

• A. Functional groups with localized electrons
• B. Functional groups with localized protons
• C. Functional groups with delocalized protons
• D. Functional groups with delocalized electrons

Hint:

Chromophores are responsible for color because the delocalized electrons absorb specific wavelengths of light.

Answer 1

The Correct Option is D

Step 1: Understanding Chromophores
Chromophores are the part of a molecule responsible for its color. These are typically functional groups with electrons that are capable of absorbing visible light.

Step 2: Role of Delocalized Electrons in Color
- Chromophores typically contain delocalized electrons, meaning the electrons are not confined to a single atom or bond but spread across several atoms.
- These delocalized electrons can absorb energy from visible light, and the absorption of specific wavelengths is what gives the molecule its color.

Step 3: Conclusion
Therefore, chromophores consist of functional groups with delocalized electrons, which are responsible for color.
