Heyyy,
Could someone please help me with this question?
Compound T, C4H10O, is oxidised by acidified potassium dichromate to form compound U, C4H8O
U gives an organe precipitate with Brady's regent, but does not give a red precipitate with heated Fehling's solution
T reacts with ethanoyl chloride to form V, C6H12O2
Find the structures of T,U and V

Thank you!

Lol i’ve seen this question... Key points are : Brady’s reagent turns orange in the presence of a C=O group. Fehlings only produces a red precipitate with Aldehydes NOT Ketones. That gives you enough information to figure out T and U. Then alcohols and acyl chlorides make esters.

oh yes I forgot that they react to give esters! I'm kind of hoping my School will just use the assessment recourses sent out by Edexcel hahah
Thank you!
