The free radical bromination of ethane includes all of the following in the reaction mechanism EXCEPT
a) bromine atom
b) ethyl radical
c) ethyl cation
d) HBr
The first mechanism includes sodium acetate to yield beta-penta-acetate and the first mechanism includes zinc chloride (Lewis acid) to form an oxonium ion to yield the alpha-penta-acetate product. Any help to draw out the mechs would be much appre..
