MCQ
Alkyl halides develop colour on:
- AAddition of water
- BAddition of non polar solvent
- CExposure to light
- DExposure to air
✓
Answer
- Exposure to light
Explanation:
Alkyl bromides and iodides develop colour when exposed to light. Halogens have lower bond dissociation energy. This low enthalpy means that even at normal temperature or on exposure to sunlight, they decompose and form free ions, which are coloured and hence impart colour on exposure to light.
