The structural formulas for the products of 1,2 and 1,4 addition of hydrogen chloride to 2,4-hexadiene are attached as a picture.
For the reaction that was shown above the H-Cl molecule is added to the first double bond during the 1,2-addition reaction, while the second double bond does not participate in the reaction itself.
However, in the 1,4-addition reaction, the first step is identical, but in the second step, the 2nd double bond has the resonance to stabilize the carbocation. As a result, the location of the double bond shifts, and Cl- is added to the fourth carbon.
The complete mechanism is attached.
