Rates of reaction of halogenoalkanes.

... Rates of reaction of halogenoalkanes. Aim; the aim of this experiment is to investigate the factors that affect the rate of nucleophilic substitution reaction. (ref1) Nucleophilic substitution is where an "electron rich" nucleophile selectively bonds with partially positive charge of an atom attached to a group or atoms called the leaving group; the positive or partially positive atom is referred to as an electrophile. Apparatus Goggles, for eye protection Test tube rack and Test tubes 250cm beaker Pipette Thermometer to measure the temperature Measuring cylinder Halogenoalkes 1. 1-Chlorobutane(C2H5Cl) 2. 1-Bromobutane(C2H5Br) 3. 1-Iodobutane(C2 H5 I) Stop Watch Diluted aqueous Sodium Hydroxide Silver Nitrate solution at 0.1 mol dm-3 Ethanol Prediction I predict that iodoalkane would react fastest because it's got the weakest bond because iodines the biggest molecule so the bond is longer and therefore weaker. The Electronegativity is factor that can have some influence in reaction of the haogenoalkane but in this case it is not as significant. In this reaction the general equation
