Question

How do you draw the structure of the reaction of 1-hexene with h2o in the presence of acid

Answer 1

If you mean the acid is a catalyst, then the major product will be 2-hexanol, because Markownikoff's Rule predicts the -OH group will go to the carbon atom with
fewer H atoms (#2 carbon in this case) and the H group goes to the C atom
with more hydrogens (#1 in this case).
