Have a little read: ... Hydroloysis of Halogenoalkanes PLAN Aim: To set up an experiment investigating the rate of hydrolysis of three halogenoalkanes at a test tube scale. Hypothesis: In this experiment the following reaction will take place: RX + H O ROH + H (aq) + X (aq) By adding the aqueous silver nitrate this will provide the hydroxide ions. The quicker the halide ions X (aq) are produced, the quicker the rate of reaction is. As iodine has the largest radius this means the electrons will be the furthest away from the nucleus than chlorine and bromine. As it can easily lose its electrons, it will react quicker with the silver nitrate and produce the X (aq) quickest. The precipitate should form in 1-iodobutane the quickest, followed by 1-bromobutane and then by 1-chlorobutane. Chlorobutane has its outer shell closest to the nucleus so it has less shielding and stronger attraction by the positively charged nucleus. The ethanol is needed to
