Alkyl Halides Lab Report

The purpose of this lab is to see the rates of the various alkyl halides by using two mechanisms which are SN1 and SN2.

a) Which alkyl chloride reacted fastest with sodium iodide in acetone: 1-chlorobutane b) Which alkyl chloride reacted slowest? 2-chloro-2-methylpropane. c) Explain how the structure of the alkyl halide affects the rate of an SN2 reaction. Primary is faster than secondary which it is faster than tertiary. d) Why doesn’t bromobenzene react? It is not Sp3 hybridized carbon.

2. a) Which halide reacted faster with sodium iodide in acetone: 1-bromobutane b) Explain how the nature of the leaving group affects the rate of an SN2 reaction. Weak bases are good leaving groups so the better …show more content…
Explain. It will be faster because iodine is a better leaving group which size increases, the ability of the leaving group to leave increases.

3. a) Which alkyl chloride reacted fastest with silver nitrate in ethanol: 2-chloro-2-methylpropane b) Which alkyl chloride reacted slowest? 1-chlorobutane c) Explain how the structure of the alkyl halide affects the rate of an SN1 reaction. It can react by a low concentration of a nucleophile or by a poor nucleophile so it is not strong enough to attack alkyl halide. So it has to separate to form reactive carbocation so it can react with poor nucleophile. d) Would you expect that the 1-chloro-2-butene would be faster than 1-chlorobutane and why? It is really complicated because they both are primary carbons which it is in SN2 reactions. I predicated that 1-chloro-2-butene will go faster because of the ranks in SN2 reaction.

There were few errors which we didn’t measure how much sodium iodine or what constituted enough precipitations to say it’s done is certainly one area of precision. Many of our measuring devices were mediocre to poor. We also have issue with time because we just winged it that may affect the
