do u mean that the CH2 will be removed and replaced by O (i know theres bond breaking/formings etc.. but for visual aid) and the double bond on the CH2 will also be replaced by a O... giving two carboxylic acids ??
... or just the double becomes a single and then forms a carboxylic and ketone...???

can u plz tell bout aldehyde

Ykov:
What's wrong with aldehyde? If it's about oxidation, yes, it can be oxidised to carboxylic acid, Cr2O72-/H+

It can also undergo reduction using 3 methods, either LiAlH4, which is kept under dry ether because it is explosive, or you can reflux it with NaBH4 or you can react it with hydrogen and a Ni/Palladium catalyst. The product is usually primary alcohols

Anything else you want to know?
