Why the aromatic carboxylic acids do not undergo Friedel-Crafts reaction?

A

Carboxyl group acts as an activating and meta-directing group

B

Carboxyl group is deactivating and act as Lewis base

C

Carboxyl group acts as an activating and ortho-directing group

D

Carboxyl group acts as deactivating group and the catalyst

Text Solution

Verified by Experts

The correct Answer is:
B

Aromatic carboxylic acids do not undergo Friedel-Craft.s reaction because the carboxyl group is deactivating and the catalyst aluminium chloride (Lewis acid) gets bonded to the carboxyl group, which facilitate the reaction at ortho and para-position.

Paragraph The acidic strength of saturated aliphatic carboxylic acids depends mainly upon the inductive effect of the substitutent and its position w.rt, the -COOH group. Whereas electron donating substitutents tend to decrease, electron withdrawing substitutents tend to increase the acid strength. The acidic strength of aromatic carboxylic acids, on the other hand, depends upon both the inductive and the resonance effect of the substitutents. Which of the following is obtained when 4-methylbenzenesulphonic acid is hydrolysed with excess of sodium acetate?
