Q)  What happens  when  cyclohexanone is heated with KMnO₄  in acidic medium ?

(actually , i thought , it results in adipic acid. but dats not d answer )

I guess the answer to this question all depends on how you run the reaction.  Under strong enough conditions, you will get adipic acid (using chromic anhydride, etc...).  If not, I would guess you'll get 6-hydroxyhexanoic acid, which may eliminate under acidic conditions to give 5-hexenoic acid (although this reaction isn't usually done with KMnO4 - usually done with ironsulfate and copper).

I'm guessing that if you tried to run this reaction, you'd end up with somewhat of a mess on your hands, forming a mixture of a bunch of the things listed above.  Maybe I'm missing something, but that would be my answer based on a quick look in the literature.

this is the given answer :

2-oxo , hexan -1-oic acid

Can somebody else weigh in on this?  I don't see how that can be the correct answer, and can't find any reference that would support that transformation... Thanks...

I agree with adipic acid as a reasonable product. I wouldn't expect the 2-oxo acid, but the 6-oxo makes at least some sense, though I don't see why it shouldn't oxidize faster than cyclohexanone itself.

look at page numbered 44

and also tell me what the reaction is
