Hydrohalogenation is anadditionreactionwhere adouble bondreacts with HBr, typically following Markovnikov's Rule, leading to acarbocationintermediate. However, the presence of a radical initiator, like peroxide, shifts themechanismto a radical-mediated process, resulting in ananti-Markovnikovaddition. Thi...

Markovnikov's rule is an important rule of product forecasting in alkene electrophilic addition reaction. 马氏规则是在烯烃的亲电加成反应中预测产物的重要经验规则 ,然而它通常的表述有一定的局限性。 更多例句>> 3) Addition Rules for Alkenes 马氏加成规则 例句>> 4...
Intriguingly, we identified 1,3-cyclohexadiene as the main example that does not follow the anti-Markovnikov rule. We proceed to show that in addition to the polarity of the double bonds within a molecule, in this case, the conjugation with the allyl double bond and the specific geometric ...

e. It follows Markovnikov's rule. Which of the following species is aromatic? Explain your choice. Label each of the following compounds as AROMATIC, NON AROMATIC AND ANTI AROMATIC. Do not re-draw them, just label them. Assume these are all plan...
e. It follows Markovnikov's rule. Label the following compounds as aromatic, anti-aromatic, or non-aromatic (assume that all molecules are planar). Construct a Frost circle to demonstrate whether the following anion is aromatic or ant aromatic D...
