Some good conversionns

thx

cyclobutyl carbocation is unstable..
that's why

otherwise the H+ should have attacked the OH

as all acid base reactions are quite fast and this was a tertiary alcohol

for 1st one,
why not + charge on carbon with oH? why not C-OH cond cleavage due to oH turning h2o?
why attack only at alkene?
