The stability of carbocations is determined by the ability of the surrounding atoms or groups to donate electron density to the positively charged carbon. This is often referred to as +I effect or hyperconjugation.

The order of stability for the given carbocations can be determined as follows:

I. CH3−C+H−CH3: This is a secondary carbocation, where the positively charged carbon is surrounded by two methyl groups. These methyl groups can donate electron density to the positively charged carbon, stabilizing it.

II. CH3−C+H−OCH3: This is a secondary carbocation where one of the groups is a methoxy group (-OCH3). Oxygen is more electronegative than carbon, so it will not donate electron density as effectively as a carbon. However, it can still provide some stabilization through resonance.

III. CH3−C+H−COCH3: This is a secondary carbocation where one of the groups is a carbonyl group (-COCH3). The carbonyl group is electron withdrawing, which destabilizes the carbocation.

So, the order of stability is: I II III.
