I have a problem with reactions.
CH3-CH2-C-CH3 + (O)
THERE IS AN -OH AND A METHYL ATTACHED TO THE SINGLED OUT -C
And also the same problem, but reacting with H+
So the first reaction is an oxidation reaction, signified by the (O)....
CH3-CH2COH(CH3)2 is a tertiary alcohol, which actually resists oxidation, therefore you will have no reaction for your ...
The reaction of CH3-CH2-C-CH3 + (O) is determined when there is an methyl group attached to a carbon.
