WebI don't think the alkene will react either as potassium dichromate isn't strong enough but it will react with acidified potassium manganate which is a stronger oxidising agent. In this case you'll end up with a 1,2 diol and I think this reaction is on the A level syllabus.

Web20 Nov 2016 · The alcohol is mixed with a small quantity of potassium dichromate and sulphuric acid in a pear shaped flask. The mixture is heated gently followed by immediate distillation of the product. If the potassium dichromate solution changes colour from orange to green then an oxidation reaction has taken place with a primary or secondary alcohol. Web5 Sep 2024 · Potassium dichromate is a powerful oxidising agent as one of K 2 Cr 2 O 7 produces three moles of oxygen on reacting with dilute H 2 SO 4. The reaction can be summed up as follows: K 2 Cr 2 O 7 + 4 H 2 SO 4 → K 2 SO 4 + Cr 2 (SO 4) 3 + 4 H 2 O + 3 (O) It liberates iodine on reacting with KI as shown below:
