Which of the following would not give $2-$phenylbutane as the major product in a Friedel-Crafts alkylation reaction?

Explain the concept of retention of configuration in a chemical reaction with an example.

What is the product formed when $1$-chlorobutane is treated with alcoholic potash $(KOH)$?

The order of reactivity of the following compounds towards the $S_{N}1$ reaction will be:
$(I)$ Benzyl chloride
$(II)$ $p$-Methoxybenzyl chloride
$(III)$ $p$-Nitrobenzyl chloride

Given below are two statements:
Statement $I$: $(Et)_2N-CH_2CH_2Cl$ will undergo alkaline hydrolysis at a faster rate than $(Et)_2CH-CH_2CH_2Cl$.
Statement $II$: Intramolecular substitution takes place first by involving the lone pair of electrons on nitrogen.
In the light of the above statements,choose the most appropriate answer from the options given below:

What is the major product formed when $2$-bromopentane reacts with alcoholic $KOH$?
