Anhydrous AlCl(3) is used as a catalyst ...

Anhydrous `AlCl_(3)` is used as a catalyst in the friedel-crafts reaction because it is

A

an electron-rich molecule

B

solution in ether

C

ionizable to `Al^(3+)` and `Cl^(-)`

D

an electr-deficient molecule

Text Solution

Verified by Experts

The correct Answer is:
D

In anhydrous `AlCl_(3)` the octet of Al is not complete. Thus it is an electron deficient species abnd acts as a lewis acid:

Friedel Craft Reaction

Friedel-Crafts reaction is not given by:

Alkylation of aromatic compounds with aliphatic compounds like halides in presence of Lewis acid catalyst is known as Friedel-Crafts alkylation. It is an exapmle of electrophilic substitution. In the process of acylation, R-overset(O)overset(||)C- group is introduced to the ring. Compounds having ( + mesomeric groups) like -NH_(2) do not give Friedel-Crafts reaction because these compounds undergo conjugation with the catalyst. In the alkylation process, most branched alkyl group is substituted because isomerisation of carbonium ion takes place. In some Friedel-Crafts reactions, the nature of product changes with the solvent used in the reaction. Predict whether the following statements are ture or false: AlCl_(3) (aq.) is used as catalst in Frieded-Crafts reaction: (a) True (b) False

In a Friedel-Crafts reaction, the electrophile is:

What is the amount of catalyst required in the Friedel-crafts acylation?

Product of the above Friedel-Craft reaction is:
