How would water be used in this reaction?
Well that above the water is competes with bromine
If H2O is present as the solvent, then it would be halohydrin. No solvent, just br2 alone then it's a halogenation
On the phone app, I can't see what you wrote I will take a look.
@abb0t did i do this right?
what is this?
Yes I am.
And yes, this is right. But...
With bromination, you can have enantiomers.
Oh yes i do. But is it right besides the racemic stuff?
SeaRocks, why are ou interrupting?!!?
^That's the correct way.
i guess the question you could ask yourself is why does water compete with bromine
I think water attacks the less hindered side, from the opposite side.
Actually, i was confused because i did the mechanism for Br2 only without the solvent. When i did that, there was no space for H2O to take place. I should've did the other mechanism where Br2 and H2O both takes place.
Yeah if you use just Br2 or maybe some other a protic solvent both bromines will be placed on the double bond.
Try this: |dw:1447035634276:dw|
The first one is halohydrin, and the second one is halogenation. I messed up on those two.
This is also addition reaction (in case you were wondering)
Uh, why did you add water?
That's already -10
i was thinking of acid-catalyzed hydration >.<
Why? Yes, this is an acid, a lewis acid. But I didn't state water here.
Actually, disregard this, I think you may not have covered this yet, although, you should be once you cover markovnikov rule, which you can use to rationalize this.
It is addition reaction, but perhaps a bit more later covered in organic I
Can you go over it?
Have you learned markovnikov rule
it was pretty recent though :P
You basically have a lewis acid, an electrophile bonded to a nucleophile.
keep in mind that protins aren't the only electrophilics that can initiate an addition rxn wth double bonds.
first electrophile adds, forming a carbocation intermediate, as the Nu:\(^-\) comes in and attacks.
|dw:1447036625877:dw| I know that the elctrophile addition is when alkenes attacks a nucleophile. Pi bonds are able to act as nucleophile.
also always remember electronegativity (although it is a very basic principle, it is a very powerful tool in all fields of chemistry, specially organic and if you decide to go into solid-state chemistyr, as well). by thinking of electronegativity differences you can sort of see where addition reagents into electrophilic and nucleophilic moieties go.
|dw:1447037173518:dw| seems like there is a nucleophile and an electrophile in this bond. i'm wondering if oxygen is partially positive here in this bond and acts as an electrophile?
Yes, an electrophile.
wow great question BTW
No offense photon, but thats the ugliest drawing I have ever seen of a methylcyclopentene
