Interpretation:The manner the results ofaddition of bromine reaction experiment supports the hypothesis that this reaction proceeds via bromonium ion intermediate rather than carbocation should be given.
Concept introduction:Alkenes are considered electron-rich and undergo bromination addition reaction with
The mechanism of
In the second step, the strained bromonium ion intermediate opens while

Which has the higher boiling point, 1-butanol or 1-butanamine?arrow_forwardWhat are the key breakdown fragmentation pathways of the product 4-methoxyphenyl acetate?arrow_forwardWhat would the resulting products of bromine to trans-stilbene look like if the bromonium ion did NOT prevent free rotation?arrow_forward
- To what structural effect do you attribute the preference of methyl bromide over t-butyl bromide in an SN2 reaction? inductive effect a. b. hyperconjugation steric effect C.arrow_forwardWhich one of the following statements about arene oxides is FALSE? O The NIH shift is what makes arene oxides carcinogenic. O Ring opening of an arene oxide can afford an addition product and/or a rearranged product. O Large polycyclic aromatic hydrocarbons such as benzo[a]pyrene are especially susceptible to arene oxide formation. The NIH shift mechanism was discovered at the National Institutes of Health. O Cytochrome P450 is the powerful biological oxidant that epoxides an arene to give an arene oxide.arrow_forward2.
