okay guys this question is taken out of topscore -test 2- number 90.

when (S)-2-iodobutane is reacted under SN2 coniditons with methanol, what will be the major product?


CH3

H3CO- C-H
|
C2H5

In general im not sure when we switch from R conig to S config....

please help me out!
 
the structre doesnt come out right...when i post it...

methyl and C2H5 should be joined with the middle carbon.....
 
        CH3
         |
H3CO- C-H
         |
        C2H5

is this sort of what you were trying to diagram?
 
ok i think i got it....i knoew about the inversion of config...during an SN2 rxn...but i was aware of the stereochem rules...on how you have to switch the lowest prorirty group facing away from you....thanks guys
