- AChloroethane
- BEthanol
- CEthanal
- ✓Ethylene glycol
✓
Answer
Correct option: D.
Ethylene glycol
Among given compounds, ethylene glycol $\left(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{OH}\right)$ is the most soluble in water. Ethylene glycol has two hydroxy groups both of which form hydrogen bonds with water. Greater is the number of hydrogen bonds, greater is the extent of hydrogen bonding and greater is the solubility in water.
