Distillation is a widely used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points , into the gas phase .
for it to be balanced in this case would be " <em>4</em> C6H6 + <em>6</em> CI2 = <em>3</em> C6H5CI + <em>9</em> HCI" therefore it's be a <u>Double Replacement</u>
Noice but I don’t get why was this necessary
Answer:
London dispersion forces
Explanation:
Intermolecular forces are the forces that facilitate interaction between solute and solvent molecules and thereby impact their solubility. These forces are broadly classified into four types arranged below from the strongest to the weakest:
1) Ionic > 2) Hydrogen bonding >3) Dipole-dipole >4) London dispersion
The hydrocarbons n-pentane 
and n--hexane 
are non-polar molecules. Therefore the only type of interaction that exists between them when forming a homogeneous solution are the weak london dispersion forces.
