Is it possible to oxidise t-butyl alcohol using acidified dichromate to form a carbonyl compound.

Explanation

`3^(@)`-alcohols do not undergo oxidation reaction under normal condition, but at elevated temperature, under strong oxidising agent cleavage of C - C bond takes place to give a mixture of carboxylic acid.
Yes, it is possible. `t` - butyl alcohol is readily oxidising in acidic solution `(K_(2)Cr_(2)O_(7)//H_(2)SO_(4))` to a mixture of a ketone and an acid each containing lesser number of carbon atoms than the original alcohol. The oxidation presumably occur via alkenes formed through dehydration of alcohols uder acidic conditions.
