Organic Chemistry-

Synthesis (Green /Conventional)

a) Aromatic Electrophilic Substitution

i) Acetylation – Acetylation of aniline/salicylic acid.

ii) Nitration - Preparation of 4-nitrosalicylic acid

ii) Bromination - Preparation of p-bromoacetanilide

b) Aldol Condensation : Synthesis of dibenzal propanone

c) Rearrangement: Benzil-Benzilic acid rearrangement

d) Pechmann Condensation for Coumarin synthesis: Clay catalysed solid state synthesis of 7- hydroxy -4- methyl coumarin

e) Diazotization/coupling: Preparation of methyl orange

Spectroscopy: Interpretation of IR and NMR spectra of simple organic compounds (ethanol, 1-propanol, 2-propanol, methylethanoate, ethyl acetate,stilbene, ethyl acetate, propanone etc).
