SeO₂ is an oxidising agent ( selective ) oxdoses C Î± to carbonyl.

thus propanone on treatment with SeO₂ gives 2-oxopropanal ( forgive my nomenclature if wrong.hopefully the message is conveyed. :)

no sky ! A C=O is not introduced an existing C is oxidised.

arey ... its a wrong english ...

jus in the figure , we need to write a C=O at the alpha position naa ?

i wrote that only...

ofcourse it is oxidies... SeO2 is an oxidising agent... :P
