Hi chemists!

We know that, due to the effect of hyperconjugation, the trend of carbocation's stability is CH3+ < RCH2+ < R2CH+ < R3C+

I found the following information is this website : ( en.wikibooks.org/wiki/Organic_Chemistry/Introduction_to_reactions/Carbocations )

"Carbocations can also be stabilized through resonance by neighboring lone pairs or pi-electrons. In general, this stabilization is greater than one degree of substitution, so a secondary carbocation stabilized by resonance will be more stable than a tertiary carbocation with no resonance stabilization, and a primary carbocation stabilized by resonance will be more stable than a secondary carbocation with no resonance stabilization."

Is that mean that a tertiary carbocation is more stable than a primary carbocation stabilized by resonance?

Thank you

Generally, yes.
