• Amines are derivatives of ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups.
• Amines are largely used in the pharmaceutical industry
• Morphine and Demerol are used as analgesics that are pain killers
• Novocaine is used as anesthetic, and Ephedra is a very common decongestant.
• Carboxylic acids contain the carboxyl acid group. • Their names end with - oic acid.
• Two types of acids:

  • Monocarboxylic acid – with only one carboxylic group.
  • Dicarboxylic acid – with two carboxyl group.
• Carboxylic acids are organic compounds that have a carboxyl group attached to an alkyl group (RCOOH)
• One of the general methods of preparing carboxylic acids is by the oxidation
• These reactions are a common thing in biological systems done by enzymes like alcohol and aldehyde dehydrogenase found in the liver.
• These are used to break down ingested alcohols in the liver to form a less harmful form called acetate
• Only formic acid, acetic acid, and lactic acid are liquids at room temperature.
• Low molecular weight carboxylic acids are soluble in water and, therefore, lie under class S1
• Water insoluble acids dissolve in both sodium hydroxide solution and sodium bicarbonate solution, being classified under class A1
• Monocarboxylic acids are weak acids
• formic acid are strongest acid
