WebThe increasing order of the leaving group ability in a S N 2 reaction is F − < C l − < B r − < I −. Large-sized iodide ion can easily accommodate negative charge. Hence it is a good leaving group. On the other hand, small-sized fluoride ion cannot easily accommodate negative charge due to greater interelectronic repulsions. WebThe answer is that the intermediate formed from an acyl derivative has a good leaving group. In the case of an acid chloride, the leaving group is the weakly basic chloride ion. We recall that leaving group abilities are inversely related to base strength. An intermediate derived from a ketone does not have a good leaving group.

Why is OH a good leaving group? - Chemistry Stack Exchange
