Reaction mechanism:
Dibromination:
Alkene is soft nucleophile and Br2 is soft electrophile. Both will react to give 3 membered bromonium ion intermediate. Then bromide ion open up the intermediate from opposite side of ring. So in the product both bromine in opposite sides ( anti-position)
Bromination of in water solvent:
In this reaction also bromonium ion intermediate will formed. Then the intermediate opened by water molecule. Water molecule attack from back side of the bromonium ion so in the product both OH and Br in anti-position.

Question: hydration of 2,3-Dimethyl-2-butene in presence of H2SO4 or H3PO4. Draw reaction mechanism using arrows. Please indicate nucleophile, electrophile, products, show intermediate structure and name (please show which carbon carriers charges if possible), if anti/syn chemistry is involved, please indicate “anti” or “syn” at the end of the reaction equation. Please name the product. Please indicate “follow Markovnikov’s rule” or “not follow Markovnikov’s rule”. (If hydride shift is possible, please consider it and show it in your reaction)
Draw curved arrows to show the movement of electrons in this step of the mechanism.
Electrophilic addition of bromine, Br-, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH2Cl2 In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product...

Electrophilic addition of hypohalous acids to alkenes yields a 1,2-haloalcohol called a halohydrin. Halohydrin formation, however, does not result from the addition of HO-Br, for example. Instead the addition is done indirectly by reaction of the alkene with Br2 in the presence of water. The reaction also works with Cl2 to give chlorohydrins instead of bromohydrins. The reaction proceeds through a cyclic intermediate known as a bromonium ion. In the second step of the reaction, water is the nucleophile and reacts with the...
