Which reagent turns acidified potassium dichromate(VI) from orange to green with a primary alcohol?
Answer and explanation
Correct answer: A. The alcohol is oxidised to an aldehyde or carboxylic acid
- Step 1: Dichromate(VI) is an oxidising agent and is reduced to chromium(III), which is green.
Answer
The alcohol is oxidised to an aldehyde or carboxylic acid.
Why not the others: The alcohol is reduced to an alkane, The alcohol is dehydrated to an alkene and The alcohol forms an ester do not fit.
