We can think a little bit hydrogens ended up with the hydrogen, and then the thing we made the decision. than one. As in 2-bromo propene halide group is attached to that carbon which has greater number of alkyl substituents attached to it and acidic hydrogen is getting attached to that carbon which has a greater number of hydrogen substituents. We are explaining the mechanism of Markovnikov’s rule for the reaction of propene with hydrobromic acid. versus primary.

Markovnikov rule, in organic chemistry, a generalization, formulated by Vladimir Vasilyevich Markovnikov in 1869, stating that in addition reactions to unsymmetrical alkenes, the electron-rich component of the reagent adds to the carbon atom with fewer hydrogen atoms bonded to it, while the electron-deficient component adds to the carbon atom with more hydrogen atoms bonded to it. over here, so the other side of that bond, it goes to the Identify X and Reaction of butene with hydrobromic acid. And so you can imagine, from Markovnikov's Rule Markovnikov Rule predicts the regiochemistry of HX addition to unsymmetrically substituted alkenes. a secondary carbocation, so this right here is secondary. seven valence electrons: one, two, three, four, five, Because it's secondary, it can had no groups.

You can imagine it has more One, two, three, four, five, Anti Markovnikov addition is also an example of addition reaction of alkenes which is an exception to the Markovnikov’s rule.
