Q.

Major product formed during the reaction between isobutyl bromide and benzene in presence of anhydrous $AlC{l}_3$ is :

1. no reaction

2. isobutyl benzene

3. t- butyl benzene

4. n - butyl benzene

Q.

Acylation process is preferred than direct alkylation because (by the Friedel-Craft's reaction)

1. In alkylation, a poisonous gas is evolved

2. In alkylation, large amount of heat is evolved

3. In alkylation, polyalkylated product is formed

4. Alkylation is very costly

Q.

The function of anhydrous ${\text{AlCl}}_3$ in the Friedel-Craft's reaction is to:

1. To produce nucleophile

2. Absorb water

3. Absorb HCl

4. To produce electrophile

Q.

Statement-1 : Friedel-crafts reaction between benzene and acetic anhydride in the presence of anhydrous $AlC{l}_3$ yields acetophenone and not poly substituted products.
Statement-2 : Acetophenone formed, poisons the catalyst preventing further reaction.

1. Statement-1 is false but Statement-2 is true.

2. Both Statement-1 and Statement-2 are true and Statement-2 is the correct explanation of Statement-1.
   

3. Statement-1 is true but Statement-2 is false.
   
   

4. Both Statement-1 and Statement-2 are true and Statement-2 is not the correct explanation of Statement-1.
