WebThe reason more alkyl groups (“R” groups) stabilize the carbocation is because of two factors, called inductive effects and hyperconjugation. Inductive effects are relatively simple, it just means that alkyl groups are slightly electron rich and can donate some of this small electron density in to stabilize the carbocation. how many elements in avatar
