Answer:

in the fraction distillation method, two liquids such as benzene and toluene are produced from the mixture of benzene and toluene.

Explanation:

Fractional distillation is a technique used in the industries for the separation of two or more liquids from one another. In this process liquid is heated, those liquid has lower boiling point will change into vapor form and collect in the upper chamber of fractional distillation while the liquid having higher boiling point also evaporates after sometime and keep it in another chamber. In the mixture of benzene and toluene, the boiling point of benzene is lower so it evaporates earlier than toluene.

See explanation and image attached

Explanation:

Alkenes undergo hydrogenation to give the corresponding alkanes. Where the structure of the original alkene is unknown, we can deduce the structure of the alkene from the structure of the products obtained when it undergoes various chemical reactions.

Now, the fact that we obtained 2-methylhexane upon hydrogenation and the two compounds had different heats of hydrogenation means that the two compounds were geometric isomers. The original compounds must have been cis-2-methyl-3-hexene and trans-2-methyl-3-hexene.

When reacted with HCl, the same compound C7H15Cl is formed because the stereo chemistry is removed.

However, we know that the trans isomer is more stable than the cis isomer hence the cis isomer always has a higher heat of hydrogenation than the trans isomer. Thus X is cis-2-methyl-3-hexene.
