Question

Tertiary carbocation is most stable compared to secondary and primary carbocations. Give reason.

Answer 1

We all know that R group is “electron-releasing”. So it can can donate some of his electron density to the neighboring carbocation ,because it has slight negative δ- charge since carbon atom is slightly more electronegative than a hydrogen atom. and due to this the more R group attached to carbon have lower the energy and will increase the stability .So Tertiary carbocation is most stable compared to secondary and primary carbocations.
