Question

Which of the alkenes shown below would produce a chirality center upon Markovnikov hydrohalogenation?

a) CH₂=CH-CH₃
b) CH3-CH=CH₂
c) CH3-CH₂-CH=CH₂
d) CH3-CH₂-CH₂-CH=CH₂

Answer 1

Option b) CH3-CH=CH2 would produce a chirality center upon Markovnikov hydrohalogenation.

Step-by-step explanation:

The compound that would produce a chirality center upon Markovnikov hydrohalogenation is b) CH3-CH=CH2.

In Markovnikov hydrohalogenation, a hydrogen halide (such as HCl or HBr adds to an alkene, with the hydrogen attaching to the carbon with the most hydrogen atoms, and the halogen attaching to the carbon with the most alkyl groups.

In option b), the hydrogen in the hydrogen halide would attach to the carbon that already has two hydrogen atoms, resulting in the formation of a chirality center. This is because the carbon atom in the alkene is bonded to four different groups, which creates stereoisomers that are non-superimposable mirror images of each other.
