in case of isobutylene there is 6 hyperconjugative structure from same side methyl group but in case of 2-butene there is also 6 hyperconjugation but from opposite side so some part cancel out so it is less stable than isobutylene.

Well I am not too sure of that...
Does hyperconjugative effect ever cancel out????

I would also like that trans 2-butene is more stable than cis 2-butene but is it more stable than isobutene too????
