Question

Why are the uses of most organic solvents not preferred in green chemistry?
Mention four alternative ways for replacement of organic solvents.​

Answer 1

Answer:

Carbon dioxide and water are the most commonly used supercritical fluids. Supercritical CO2 and water are considered “green” solvents in many industrial processes, providing high yields in many reactions, and there are many examples of their use in the scientific literature.

Answer 2

Answer:

Chlorinated solvents should be avoided, as many of these solvents are toxic and volatile, and are implicated in the destruction of the ozone layer. ... The solvent of choice for green chemistry is water, which is a non-toxic liquid but with limited chemical compatibility.
