These are standard reactions and are very likely all covered in the alkenes/alkynes chapter of any organic chemisry text, eg. Clayden & friends.

You should at least try doing some reading before asking on the forums.

1. What is the purpose of ultraviolet light?  Can you propose a radical mechanism for this?  How is it different than addition with HBr? what about HBr with H₂O₂?

2. Sounds good.  Why is it cis?

3. What is the purpose of NaHSO₃?  Product looks good.

4. What about mercuric oxide makes it different than other oxidants? phenyl acetone? (How many carbons do you have?
