Which product (s) would be obtained by the dehydration of 2 heptanol and 2-methyl-1-cyclohexanol?

In the dehydration of alcohol, all you have to do is take out the oxygen from the - OH bond which reacts with the H + ions from the acid to produce water.

So, for 2-heptanol, the products would be water and heptane. For 2-methyl-1-cyclohexanol, the products would be water and 2-methylcyclohexane.
