List-I

List-II

(A) Wurtz-Fittig reaction

(III) Alkylarene

(B) Chiral

(IV) Non-superimposable mirror images

(C) Friedel-Crafts Acylation

(I) $CH_3COCl$ and Anhyd. $AlCl_3$

(D) Freons

(II) Swarts reaction

 

(A) Wurtz–Fittig reaction → (III) Alkylarene
Wurtz–Fittig reaction is used to prepare alkyl benzenes (alkylarenes) by reacting an aryl halide with an alkyl halide in presence of sodium in dry ether.

(B) Chiral → (IV) Non-superimposable mirror images
A chiral molecule is one whose mirror image cannot be superimposed on it. Such molecules show optical isomerism.

(C) Friedel–Crafts Acylation → (I) CH₃COCl and Anhyd. AlCl₃
Friedel–Crafts acylation introduces an acyl group into benzene using an acid chloride (like CH₃COCl) in presence of anhydrous AlCl₃ catalyst.

(D) Freons → (II) Swarts reaction
Freons (chlorofluorocarbons) are prepared by the Swarts reaction, where chlorine atoms in hydrocarbons are replaced by fluorine using metal fluorides.
