Answer

Answer 

No, the reaction occurs because the fluoride ion is a very poor leaving group

1Step1: 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.

2Step 2: Reaction of cyclohexane fluoride


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