What happens when butanol is heated with potassium dichromate and concentrated sulphuric acid

repulsive smell, something like rotten cheese. MEK, on the other hand, smells a lot like butterscotch.-Google oxidation of butan-1-ol or butan-2-ol as required.......
Answer needed for my chemistry lab discussion asap!

Potassium dichromate and sulfuric acid are used to prepare the Jones reagent, which is capable of oxidizing primary alcohols to carboxylic acids and secondary alcohols to ketones.

Assuming you're using 1-butanol, a Jones oxidation will give butanoic acid. If you're using 2-butanol, the product will be 2-butanone, also called methyl ethyl ketone (MEK). Oddly enough, butanoic acid has a very strong, repulsive smell, something like rotten cheese. MEK, on the other hand, smells a lot like butterscotch.

Google oxidation of butan-1-ol or butan-2-ol as required. You must be specific.

I wouldn't use conc H2SO4 personally for this reaction...
