List-I (Compound) |
List-II (Uses) |
|
(A). Diazonium salt |
(IV). dyes |
|
(B). Novocain |
(III). dentistry |
|
(C). Benadryl |
(II). antihistaminic drug |
|
(D). Quaternary ammonium salts |
(I). surfactants |
(A) Diazonium salt → (IV) dyes: Diazonium salts are key intermediates in the synthesis of azo dyes through azo coupling reactions with aromatic compounds (e.g., phenols or amines).
(B) Novocain → (III) dentistry: Novocain (procaine) is a local anesthetic historically and classically used in dental procedures for numbing.
(C) Benadryl → (II) antihistaminic drug: Benadryl (diphenhydramine) is a well-known antihistamine used to treat allergies, itching, and related symptoms.
(D) Quaternary ammonium salts → (I) surfactants: These compounds are cationic surfactants widely used in fabric softeners, hair conditioners, disinfectants, and detergents due to their surface-active properties.
