Synthesis (Green Methods / Conventional Methods)

a. One step synthesis

    · Aldol condensation (Synthesis of dibenzal propanone)

    · Acetylation (synthesis of acetanilide from aniline)

    · Pechmann Condensation for Coumarin synthesis (Clay catalyzed solid state                synthesis of 7-hydroxy -4-methyl coumarin)

     · Bromination of phenol

b. Two step synthesis (any three)

     · Benzoin → benzil → benzilic acid

     · Benzophenone → benzpinacol → benzpinacolone

     · Acetanilide → p-bromoacetanilide → p-bromoaniline

      · Acetanilide → p-nitroacetanilide → p-nitroaniline

      · Resorcinol → flouroscein → eosin

      · Phthalicanhydride → phthalimide → anthranilicacid
