Interpretation:
The syntheses of cyclopentene from the given compounds are to be outlined.
Concept introduction:
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called an elimination reaction.
Nucleophilic substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any nucleophile is called a nucleophilic substitution reaction.
A nucleophile is a molecule or atom with the negative charge or having lone pair on nucleophilic atom.
There are two types of nucleophilic substitution reactions:
