Question

The reactions shown below are unlikely to occur as written. Tell what is wrong with each, and predict the actual product.

Short answer

No, the reactions occurs beause the fluoride ion is a very poor leaving group.

Step-by-step solution

S N  2 reaction

It is a nucleophilic substitution reaction in which an old bond is broken and a new bond has formed. Both processes occur simultaneously. Hence, it’s a single-step reaction.

The two reacting species are involved in the rate-determining steps.

Reaction of cyclohexane fluoride

Fluoride ion is a poor leaving group because its small size and the high electronegativity so hydroxide ion cannot substitute the fluoride ion that why the given reaction does not occur.
