Assessed practical on hydrolysis of halogenoalkanes

Hydrolysis is the means in which to make an alcohol using the OH from water. Our reactants are the halogenoalkanes and hydroxide. A halogenoalkane is a hydrocarbon that has been bonded with a group7 element, for example:

* Fluorine

* Chlorine

* Bromine

* Iodine

We will only be using primary halogenoalkanes. A primary molecule is where the nucleophile is on the end. We determine the classification by looking at the carbon atom that the nucleophile is bonded with, if the carbon atom is bonded to one other carbon only it is primary, if it is bonded with two then secondary and if bonded with three then it is tertiary.

An example of a primary halogenoalkane would be 1-bromobutane:

H³C-CH²-CH²-CH²-Br

All of the C-X bonds are polar, the bond enthalpy's for a C-F bond is 467Kj/mol, for a C-Cl bond is 340Kj/mol, for bromine it is 280Kj/mol and for iodine it is 240Kj/mol. These numbers reefer to the amount of energy in kilorjewls taken to break he bonds, I got this information from the AS CHEM WORKBOOK. From this information I know that the Fluorine
