Harry Denis Candidate No. 9038 Centre No. 10534 Plan for rate of reaction for halogenoalkanes Aim Aim of the experiment is to find out and compare the rate of displacement of the halide ion and how is varies with respect to the carbon halogen bond. This will occur through a nucleophilic attack. General equation: general formula: R-X +: Nu- ? R-Nu + X- CnH2n+1X (where X is the halogen) Background information halogenoalkanes In the reaction of halogenoalkanes bond polarity show us that C-F would be the most reactive then C-CL, C-Br and C-I would be the lest reactive. This is due to the electronegativity of the halogen atoms. Electronegativity is the measure of how strongly an atom in a compound attaches electron in a bond. The greater the difference in the electronegativity of two atoms, the more polar is the covalent bond between the two atoms. So in a carbon halogen bond the halogen is more electronegative than carbon....
