For my organic chem class we were given a small project of trying to find out the mechanism for several different things. I have been working on this for the last 2 weeks and have not gotten anywhere yet.

Any help would be great, and not sure if i am allowed to give that person money via paypal if they can solve the entire problem for me...

thanks

show us what you've got so far and we'll help you through.

first (and most important) hint:  for each reaction, label the nucleophile.  label the electrophile.  nucleophiles attack electrophiles.  repeat.

Theres actually another 6 problems which I was able to get, these ones ive posted im totally lost on.

I was actually able to kinda workout the last 2 attachments, the ones with the boxes.

They wernt that bad once i was able to find some other examples online that were similar.

BUT i still havnt gotten the first part with the two mechanisms.

OK, for part 1 what does bromine do to double bonds?

For part 2 what's the nature of your reactants?

+ problem 1 :
U can understand like  the reaction react following Ae mechanism:
Br+--Br- attach  CH=CH to form CHBr-CH+ and this cationic was stable by Oxgen 
after that's the OH attach by intramolecular cyclization reaction. done
+problem 2 :
that's not very difficult. firstly, starting metarial is 1-methylcyclohexane, second, 1-bromo-1-methylcyclohexan, following, 1-methylcyclohex-1-ene, heptan-2,7-dion. done
P.3:
so easy, ====>1- butene , then ,  1,2-dibromobutane, then== buta-1-ine and hexa-3-ine , then hexene-3, then hexa-3,4-diol. done
