addition of hcl to alkene

What type of reaction is alkene?
The most common type of reaction for alkene is the addition reaction to a C=C double bond. In addition reaction, a small molecule is added to multiple bonds, and one π bond is converted to two σ bonds (unsaturation degree decreases) as a result of the addition. An addition reaction is the opposite process of elimination.
What happens when halogen is added to an alkene?
The reaction tends to occur such that the halogen ends up attached to the carbon of the alkene attached to the fewest hydrogen atoms, a phenomenon known as Markovnikov’s Rule. Addition of H-X to alkenes occurs through a protonation of the alkene to give a carbocation intermediate, followed by addition of the halide to the carbocation.
What happens when HCL is added to ethene?
All alkenes undergo addition reactions with the hydrogen halides. A hydrogen atom joins to one of the carbon atoms originally in the double bond, and a halogen atom to the other. For example, with ethene and hydrogen chloride, you get chloroethane: Figure 7.8.1 7.8. 1 Electrophilic addition of HCl to ethene.
What happens when hydrohalic acids are added to alkenes?
When hydrohalic acids (HCl, HBr, HI) are added to alkenes, addition reactions can occur, resulting in formation of a C-H and C-halogen bond and breakage of a C-C pi bond. The reaction tends to occur such that the halogen ends up attached to the carbon of the alkene attached to the fewest hydrogen atoms, a phenomenon known as Markovnikov’s Rule.
