Most books I have read stop at this order :
Benzylic > Allylic > Tertiary > secondary > primary
However If I want to compare tertiary, secondary and primary benzylic and Allylic carbocations what will be their stability order?
Yes tertiary allyllic carbocation is more stable than secondary because no. of electrone donating methyl groups are greater than secondary (in tertiary 3 methyl groups while in secondary are 2) so they decrease electrophilicity carbocation but it still it remain electrophillic.
