The bond resonance is not dependent upon the number of
α−H
Consider the structure of But-1-ene.
CH3−CH2−CH=CH2
But-1-ene possesses 2α−H. So, it gives two no bond resonating structures.
Consider thestructure of 3∘ carbocation.
The 3∘ carbocation contains 7α−H bond. Therefore, it forms 7 no bond resonating structures.
