Nitro Compounds
These are obtained by replacing one H of hydrocarbon by -NO2 group . These are named according to IUPAC system as ‘ nitro alkane ’.
Methods of Preparation
( i ) From alkyl halides
Physical Properties
1 . These are colourless pleasent smelling liquids .
2 . Their boiling point are much higher than isomeric alkyl nitriles . 3 . These are less soluble in water but readily soluble in organic solvents .
Chemical Properties
( i ) Reduction With Sn / HCl or catalytic hydrogenation , nitroalkanes are reduced to amines .
