WebA substitution reaction is a reaction in which an atom, ion, or group of atoms or ions are replaced by another atom, ion, or group (Britannica, 2009). In this experiment the OH in the tert-butyl alcohol is replaced by Cl in hydrochloric acid (HCl) making the product tert-butyl chloride. Thus, we were able to prepare tert-butyl chloride by ...
Web13 jul. 2012 · The best explanation for how this reaction works is that it begins with a (rate-determining) loss of a leaving group to give a carbocation, which can then undergo attack by a weak nucleophile at either face, resulting in the loss of stereochemistry. The SN1 reaction is sometimes accompanied by carbocation rearrangements. Table of Contents chris leduc baselWebThe FTIR showed that the SN1 reaction took place because the OH group was not present on the t-butyl chloride stretch. The reaction started off with an OH and was substituted by the chloride in the product. Figure 2. t-Butyl Alcohol and t-Butyl Chloride Charts.
