Answer :
The addition of HBr to an alkene under free-radical conditions is governed by the addition of a Br atom to the alkene to give the most stable alkyl radical possible. The addition of HBr in the absence of radicals is governed by the addition of a proton to the double bond to give the most stable carbocation possible.
A carbocation is a molecule wherein a carbon atom has a fine fee and three bonds. we will basically say that they are carbon cations. formerly, it turned into referred to as carbonium ion. Carbocation these days is defined as any even-electron cation that possesses a big effective charge at the carbon atom.
Carbocation and carbanion are unique forms of carbon atom molecules that bring one-of-a-kind electric fees. Carbocation atoms are carbon plus cation, and consequently, they have a wonderful rate. similarly, carbanion is a mixture of carbon and anion and includes terrible expenses.
