Introduction
► An
inorganic nonaqueous solvent is a solvent
other than water, that is not an organic
compound. examples are liquid ammonia, liquid
sulfur dioxide, sulfuryl chloride and sulfurychloride
fluridef, phosphoryl chloride, dinitrogen tetroxide,
antimony trichloride, bromine pentafluoride,
hydrogen fluoride, pure sulfuric acid and other
inorganic acids. These solvents are used in
chemical research and industry for reactions.
Question
► Is
non aqueous solvent ?
A. NH3
B.Liquid SO2
C.HF
D.All
Classification of solvents
► Classification
of solvents based on
proton.
► Classification of solvents based on
polar and non-polar solvents.
► Classification of solvents on Aqueous
and non- aqueous solvents
►Protic
or protoni solvents
2NH3 ⇌ NH4+ (ammonium) + NH2− (amide)
3HF ⇌ H2F+ + HF2- (hydrogen difluoride)
2H2SO4 ⇌ H3SO4+ + HSO4-
 (A)Acidic or protogenic solvents.
H2SO4,HCL,CH3COOH,HCN.
 (B) Basic or protophilic solvents.
NH3, N2H4.
►Aprotic
►
or non- protonic solvents.
C6H6,CHCl3,CCl4,SO2.
N2O4 ⇌ NO+ (nitrosonium) + NO3− (nitrate)
2SbCl3 ⇌ SbCl2+ (dichloroantimonium) + SbCl4(tetrachloroantimonate)
POCl3 ⇌ POCl2+ + POCl4-
