    I had a lab on the dehydration of cyclohexanol and I am not trying to understand certain concepts. Here are some questions I am trying to figure out:

    - The product ratio is Saytzeff > Hofmann for both E1 and E2 reactions. What causes this to be the case for each reaction? I understand slightly that for E2 its steric hindrance and for E1 its competition or something.

    - What exactly is the reduction of alkynes? I just understand that it is a method for synthesizing alkenes.

    -Why are the leaving groups for E2 reactions not as good as E1 reactions?

    -Why don't E2 reactions rearrange?

    - the solvents for both reactions are unimportant...correct?

    -How does E2 support the zaitsev's rule? (in other words, what do the products illustrate?)

    - When I performed the dehydration, I thought we successfully synthesized an alkene because the bromine test was positive. However, when we did an IR, and that showed an O-H bond which is not good because that should only appear on an IR test for a cyclohexanol not a cyclohexane. Why did this occur?
