WebJan 14, 2005 · Can K2Cr2O7 oxidize salicylic acid? I'm studying chemistry lab and I've done the experiment and the result show that it can't but I'm not sure. The others phenolic compound that I have tested show positive result, for example , alpha-naphthol. Why can't salicylic be oxidized? Please explain. Thanks for your reply. WebAnswer (1 of 3): The above flowchart indicates on how KMnO4 ( Pottasium permanganate ) oxidises the double bond( Alkene ).

WebThe oxidation of secondary alcohols to ketones is an important oxidation reaction in organic chemistry . When a secondary alcohol is oxidised, it is converted to a ketone. The hydrogen from the hydroxyl group is lost along with the hydrogen bonded to the carbon attached to oxygen. The remaining oxygen then forms double bonds with the carbon. WebVitamin D4 (structure shown) can be oxidized by K2Cr2O7 to give a ketone. A. True. B. False. 2.) What is the shape around the C (1) atom and around the O (2) atom in the …
WebOn the other hand, a primary alcohol (such as 1-butanol) will be readily oxidized, even under mild conditions and with reagents much gentler than $\ce{K2Cr2O7}$. With heating and sufficiently acidic conditions, a tertiary alcohol can be eliminated to form an alkene, which can then be oxidatively cleaved to yield two molecules with carbonyl groups. WebPotassium dichromate, K 2 Cr 2 O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications.
