Nucleophilic acyl substitution describes a class of substitution reactions involving nucleophiles and acyl compounds. An acid derivative has a leaving group, which is substituted by a nucleophile. If the leaving group is more stable than the nucleophile (weaker in terms of basicity), then the reaction is energetically favorable and occurs readily. If the nucleophile is more stable than the leaving group, then the reaction is enegetically unfavorble and does not occur readilty. This can be explained on the basis of the stability ladder below:

An acyl substitution that converts an acid derivative from a higher rung on the stability ladder to one on a lower rung of the ladder is energetically favorable. An acyl substitution that converts an acid derivative from a lower rung on the stability ladder to one on a higher rung of the ladder is energetically unfavorable.

This is an example of a nucleophilic acyl substitution reaction in which an anhydride is getting converted into an acyl chloride. An acid derivative has a leaving group, which is substituted by a nucleophile. If the leaving group is more stable than the nucleophile (weaker in terms of basicity), then the reaction is energetically favorable and occurs readily. If the nucleophile is more stable than the leaving group, then the reaction is enegetically unfavorble and does not occur readilty. This can be explained on the basis of the stability ladder below:

Interpretation:

It is to be indicated whether the given conversions would be energetically favorable or unfavourable. Also, it is to be given if the reaction is likely to occur readily.

Concept introduction:

Nucleophilic acyl substitution describes a class of substitution reactions involving nucleophiles and acyl compounds. An acid derivative has a leaving group, which is substituted by a nucleophile. If the leaving group is more stable than the nucleophile (weaker in terms of basicity), then the reaction is energetically favorable and occurs readily. If the nucleophile is more stable than the leaving group, then the reaction is enegetically unfavorble and does not occur readilty. This can be explained on the basis of the stability ladder below:

An acyl substitution that converts an acid derivative from a higher rung on the stability ladder to one on a lower rung of the ladder is energetically favorable. An acyl substitution that converts an acid derivative from a lower rung on the stability ladder to one on a higher rung of the ladder is energetically unfavorable.

Expert Solution

Answer to Problem 20.5YT

Explanation of Solution

The given reaction is

Organic Chemistry: Principles And Mechanisms, Chapter 20, Problem 20.5YT , additional homework tip 11

This is an example of a nucleophilic acyl substitution reaction in which an acid anhydride is getting converted into dicarboxylic acid. If the leaving group is more stable than the nucleophile (weaker in terms of basicity), then the reaction is energetically favorable and occurs readily. If the nucleophile is more stable than the leaving group, then the reaction is enegetically unfavorble and does not occur readilty. This can be explained on the basis of the stability ladder below:

An acyl substitution that converts an acid derivative from a higher rung on the stability ladder to one on a lower rung of the ladder is energetically favorable. An acyl substitution that converts an acid derivative from a lower rung on the stability ladder to one on a higher rung of the ladder is energetically unfavorable.

Referring to this chart, an acid anhydride is from a higher rung while a carboxylic acid is from a lower rung on the stability ladder. Thus, this reaction is energetically favorable and occurs readily.

Conclusion

Conversion of an acid derivative from a higher rung to lower rung on the stability ladder is energetically favourable, and the reaction occurs readily.
