Non-coordinating solvents
Examples of this type include carbonatertrachloride, saturated hydrocarbons, fluorocarbons etc. These solvents are not of much interest to a chemist because of their inertness.
Although a large number of non-aqueous solvents have been investigated in detail, the discussion in this chapter will be confined only to a few representative solvents: liquide ammonia (a basic protonic solvent), liquid HF and H2SO4 (strongly acidic protonic solvents) and liquid sulphur dioxide (a non-protonic solvent).
There are a number of physical properties of a solvent that are of great importance in determining its behavior and in fact its usefulness as a solvent. These are :
1. The temperature range over which it is a liquid, i.e. liquid range
2. Dielectric constant
3. Donor and acceptor properties, i.e., its Lewis acid base behavior
4. Extent of self-dissociation
5. Heat of fusion and vaporization
6. Viscosity and density.
