Step 1
The major product in the reaction of HCl with the 2-methylpent-2-ene is
Answer
To determine the major product formed when HCl reacts with 2-methylpent-2-ene, we need to identify the carbon atoms in the double bond.
2-methylpent-2-ene has a double bond between the second and third carbon atoms. The carbon at the second position has one hydrogen attached while the carbon at the third position has no hydrogen atoms attached. According to Markovnikov's rule, the hydrogen from HCl will attach to the carbon that has more hydrogen atoms.
Thus, in this case, the H will add to the carbon at the second position, resulting in the addition of the Cl atom to the third position. The product that will be formed here corresponds to option B.
