Question

According to Markovnikov's rule, when 3-methyl-1-butane undergoes and addition reaction with HCl, the chlorine will end up on which main chain carbon?

Answer 1

According to Markovnikov's rule, the chlorine will end up on the third main chain carbon.

Step-by-step explanation:

In the addition reaction of 3-methyl-1-butane with HCl, the chlorine will end up on the third carbon atom in the main chain. This is because Markovnikov's rule states that in the addition of a hydrogen halide to an unsymmetrical alkene, the hydrogen atom attaches to the carbon atom with the most hydrogens, while the halogen atom attaches to the carbon atom with fewer hydrogens. In this case, the third carbon has fewer hydrogens than the second or fourth carbon, so the chlorine will attach there.
