Amines are derivatives of ammonia. They are obtained by replacing hydrogen atom by alkyl or aryl group. Either one or two or all the three hydrogen atoms are replaced. Based on the number of hydrogen atoms replaced, amines are classified into three: Primary, Secondary and Tertiary amines.
Primary amines are formed when one hydrogen atom of ammonia is replaced by R or Ar. Secondary amines are formed when two hydrogen atoms of ammonia or one hydrogen atom of R-NH2 is replaced by alkyl or aryl group. When all the three hydrogen atoms of NH3 are replaced by alkyl or aryl group it is called tertiary amine. This was a brief on Chemical Kinetics.
