Description: Primary and secondary alcohols are oxidized by K2Cr2O7 to carboxylic acids and ketones respectively. The oxidation is physically observed by the change in color upon reduction of Cr6+ (yellow) to Cr3+ (blue).

Can K2Cr2O7 oxidise alkene?

Take note that K2Cr2O7 cannot oxidise Alkenes at all this is because Pottasium Dichromate (K2Cr2O7) is not strong enough to oxidise Alkenes.

Why is K2Cr2O7 an oxidizing agent?

Potassium dichromate is a good oxidizing agent because when elements come into its contact in a chemical reaction they become more electronegative as their atom’s oxidation state increases.
