I was thinking of dehydrating this alcohol:
Its structure is:
My concern is which of the following would it form:
The problem is that the first one comes from a stable benzyl secondary carbocation while the second one comes from a secondary carbocation but forms a more substituted alkene. Which one is preferred and why? (I feel that the second one should be preferred because of Saytzeff's (Zaitzev's) rule stating that more substituted alkene is formed)
Given answer was that the first one is formed (that too trans, which is I know why). But why the first one?
