3. Anhydride AlCl₃                     

4.Conc. H₂SO₄

Oxidation of allylic alcohol, (CH₂=CH-CH₂OH) gives a mixture of oxalic acid and formic acid. If this oxidation is done in presence of bromine. One would expect only:

1. Oxalic acid

2. Formic acid

3. Succinic acid

4. Acrylic acid

Consider the following reaction,
