39Tumhara matlab jaise jab methyl groups attached hote hain C=O pe, nucleophilic addition kam hota hai...
In a sense this is correct. More stable(read : more substituted) the carbocation formed by electromeric effect, lesser is the chance of nucleophilic addition.
Rather than checking the stability of carbocation, we check the steric hindrance of the C atom involved for nucleophilic addition, because electromeric effect is temporary and occurs in presence of reagent.
Electromeric effect and carbocations are diff...should not be judged together.
