Why is dichloromethane used in bromination

They are stereoisomers, and furthermore, they are enantiomers or mirror images of each other. Does it matter if the solvent is polar protic or aprotic for bromination to occur? Such as Br2, THF adding to the alkene? Why alkene give alpha halo alcohol with bromine water while it gives bromo alkene with bromine and carbon tetra chloride??

Observation 2- I had this exact problem on an organic chemistry quiz. The teacher said it needed an OH group… please explain. Hi, I have been trying to do a Bromination reaction. What product are you trying to obtain? When you activate the oxygen with PBr3 there is the possibility for anchimeric assistance from either the oxygen or the carbonyl in the ester.

H2O is not a better nucleophile than Br-, but if H2O is present in large excess e. Your email address will not be published.
