a) propanol
b) 2-methylcyclohexanol

Answer 1

This is fascinating:

Look at the structure of propanol:



The addition of acid and heat causes a dehydration reaction.

Well, in this case, it's through an E1 mechanism

The lone pair of electrons goes from the oxygen on the propanol to the oxygen on the sulfur. remember acids are electron acceptors bases are electron donors

Answer 2

If you notice something, the acid is actually regenerated, that's because we use a catalytic amount of acid which gives us this alkene.
