What is a factional distillation and how would you figure out how many fractional distillation would C4H8CL2 isomers have.

You can read about fractional distillation here.

http://en.wikipedia.org/wiki/Fractional_distillation

In simple language, each component of a mixture that has a different boiling point will distill and be separated into its fractions, hence the name.
To determine the number of fractions you will get from your compound, you will first need to determine the number of possible isomers, look up the boiling point of each, and IF THE BOILING POINTS ARE SUFFICIENTLY DIFFERENT, then you could separate each of them.

Just a few tips when working out isomers for a molecular formula such as this.

1. If the molecular formula corresponds to Cn(Monovalent)2n+2 there are no double bonds/rings to be taken into account. Here it is C4(Monovalent)10 which corresponds to the formula so there are no double donds or rings. [There is a formula which calculates the number of double bond equivalents, but I do not need to complicate things]
2. Decide on the hydrocarbon structures that are possible. There are only 2 here.
3. Using the hydrocarbon structures replace the H atoms, in this case with Cl atoms. There are a number of isomers, about 9 but I have only doodled on a envelope, plus some optical isomers.

In your answer I would note the optical isomers but the optical isomers can't be separated by fractional distillation.

Good luck, it is an interesting question.

Fractional distillation is a process used to separate a mixture of liquids with different boiling points. It takes advantage of the fact that each component of the mixture vaporizes at a different temperature. By heating the mixture and collecting the condensed vapors at different temperature ranges, you can separate the different components.

To figure out the number of isomers that C4H8Cl2 (1,2-dichlorobutane) has using fractional distillation, we need to consider the different arrangements of atoms in the molecule. Isomers are compounds that have the same molecular formula but different structural arrangements.

Here is one way to determine the number of isomers for C4H8Cl2 using fractional distillation:

1. Start by generating all possible structural arrangements for the given molecular formula. In this case, we have C4H8Cl2. The possible isomers can be created by moving the Cl atoms to different positions on the hydrocarbon chain.

2. Draw the structural formula for each isomer. By rearranging the Cl atoms on the carbon chain, you will get different isomers. For example, you could have 1,2-dichlorobutane (Cl-CH2-CH2-CH2-Cl), 1,3-dichlorobutane (CH3-CH(Cl)-CH2-CH2-Cl), 1,4-dichlorobutane (CH3-CH2-CH(Cl)-CH2-Cl), and so on.

3. Once you have all the possible isomers, you can separate them using fractional distillation. The boiling points of these isomers will be different due to the varying molecular structures. By carefully controlling the temperature during distillation, you can collect each isomer separately as it evaporates and condenses.

In summary, the number of isomers for C4H8Cl2 can be determined by generating and identifying all possible structural arrangements of the atoms in the molecule. Fractional distillation can then be used to separate these isomers based on their different boiling points.
