Function of $\mathrm{AlCl}_3$ in Friedel-Craft's reaction is to
1 produce electrophile
2 break bond
3 produce nucleophile
4 make new bond
Explanation:
: $\mathrm{AlCl}_3$ is a lewis acid catalyst is aluminium trichloride because the product ketone forms a rather stable complex with lewis acid such as $\mathrm{AlCl}_3$. a stiochiometric amount or more of the catalyst must generally employed. $\mathrm{AlCl}_3$ Will coordinate to halogens and facilitate the breaking of these bonds. It increase the electrophilicity of it's binding partner make it more reactive.

2-bromopentane with alcoholic $\mathrm{KOH}$ yields a mixture of three alkenes. Which of the following alkene is predominant?
1 1-pentene
2 Cis-2-pentene
3 Trans-2-pentene
4 Cis-1-pentene
Explanation:
: According to the Satyzeff rule, trans alkene are more stable than cis. So, the option (c) is correct.

The reaction $\mathrm{C}_6 \mathrm{H}_6+\mathrm{CH}_3 \mathrm{Cl} \stackrel{\mathrm{AlCl}_3}{\longrightarrow} \mathrm{HCl}+\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_3$ is called
1 addition reaction
2 Friedel-craft acylation
3 Friedel-craft alkylation
4 Friedel-craft benzoylation
Explanation:
: Benzene react with alkyl chloride (Methyl chloride) in the presence of $\mathrm{AlCl}_3$ then the product is formed toluene. This reaction is known of friedal -craft alkylation.
