Preparation of Polyesters They are polymers those can be produced by polymerization of esters formed due to condensation reaction between di-carboxyllic acid & di-hydric alcohol.…

Preparation of Esters: From acid by Esterification: If carboxylic acid & alcohol are heated with conc. H2SO4 or HC1(g), ester & water are produced. The…

Esters are derivative of carboxylic acids in which the -OH group has been replaced by -OR group, where R may be an alkyl / aryl…

Physical properties of Acid Derivatives: 1. Acid chloride, Ester & Acid Anhydride: Volatileness: Acid chloride, ester & acid anhydrides can’t form H-bond by themselves. So…

Uses of Different Acids and Their Derivatives Compound Name: Acid Anhydride. Uses: As a regent in acetylation reaction Production of aspirin As a solvent of…

Production of Aspirin The acid anhydride is used as an acylation reagent. When phenol is heated with Carbon dioxide (CO2) and Sodium hydroxide (NaOH) at…

Hell Volhard – Zelinsky reaction: When a carboxylic acid that contains α-hydrogen is treated with Cl2 or Br2 in the presence of red phosphorus, the…

They are weak acids and weaker than mineral acids. Only 0.5% of one molar ethanoic acid is ionized at normal temperature. Only 03 molecules in…

Rosenmund’s Reaction: When acetyl chloride is reduced with hydrogen in the presence of ‘poisoned’ palladium catalyst, it forms aldehydes. This reaction is called Rosenmund’s reaction.…

Physical Properties of Carboxylic Acids: (i) Physical state: The first nine members (C1 ≈ C9) are colorless, pungent smelling liquids. The higher members are colorless,…
