Which of the following statements describes accurately the mechanism of the bromination of alkenes? Choose all that apply. O As a consequence of the cylic bromonium ion and anti-addition, a maximum two stereoisomers are formed even though the dihalide product may have two chiral carbons. O Instead of a carbocation intermediate, bromination forms a cyclic bromonium intermediate. O A symmetric cis alkene will form only stereoisomer that is a meso compound O The mechanism of the bromination of alkenes is absolutely the same as the general mechanism of electrophilic addition of alkenes. O The bromide ion can only add to the side opposite the C-Br bonds of the bromonium ion because of steric hindrance.
Use the Text Submission box to answer the following question. Consider the reaction shown below. For a particular concentration of sodium methoxide, the absorbance at 244 nm is measured using UV-vis spectroscopy. Over an initial period, the absorbance at 244 nm increases from 0.50 to 0.60. When the concentration of sodium methoxide is doubled, the absorbance at 244 nm measured after the same initial period is 0.70. What can you conclude about the mechanism of the reaction? NaOCH 3 Amax = 244 nm
Question: How do quantum mechanical effects influence the stability and reactivity of molecules with non-classical carbocations, such as the 2-norbornyl cation, and how does this impact the reaction mechanisms and outcomes?
