Question

criteria to become good solvent in NMR , IR and UV​

Answer 1

Answer:

1 . Solvent should have good dissolving power.

2. It should not contain any impurities.

3. A good solvent should not itself absorb radiation in region under investigation.

4. It should be less polar so that it has minimum interaction with solute molecules.

Ex. solvents in NMR : 1. CCl4, 2.D2O, 3. CDCl3 ( Both solid and liquid solvents are used) .

Solvents used in IR : 1 CCl4 , 2. CS2

Solvents used in UV : Ethanol, chloroform, benzene, CCl4.
