Which is most VISCOUS?
- A Ethanol
- B Ethylene glycol
- C Glycerol
- D Methanol
Answer & Solution
Correct Answer
(C) Glycerol
Step-by-step Solution
Detailed explanation
We know that, higher is the extent of H-bonding higher will be the viscosity.
Among the given option glycerol has the highest viscosity as in this case 3-0H groups are involved in hydrogen bonding which is greater than other ethylene glycol has two and both ethanol and methanol has one \(-\mathrm{OH}\) group.
