Answer:
The Correct Option is 3) Urea in Water
Explanation:
It s found that urea incorporates readily into water, forming pronounced hydrogen bonds with water at both the amine and carbonyl headgroups.
In addition the urea also hydrogen bonds to itself, forming chains or clusters consisting of up to approximately 60 urea molecules in a cluster.
In comparison with the traditional methods and solvents, aqueous alkali/urea solutions proved to be a stable and more homogeneous medium for preparing chitosan ethers with higher DS through a one-step reaction.
