To match the names of the reactions given in Column I with the appropriate reactions given in Column II, let's analyze each reaction and its equation.
1. Sandmeyer Reaction:
This reaction involves the replacement of the diazonium group with another substituent using coppe salts. The correct equation corresponding to this reaction is:
C6H5N2+Cl−+Cu2Br2∕HBr⟶C6H5Br+N2 2. Fittig Reaction:
The Fittig reaction is similar to the Wurtz reaction, involving the coupling of aryl halides using sodium in dry ether to form biaryl compounds. The appropriate equation for this reaction is:
2C6H5Cl+Na (dry ether) ⟶ Diphenyl. 3. Swarts Reaction:
This reaction involves the exchange of a halogen atom in an alkyl halide for fluorine using a metallic fluoride. The corresponding equation is:
CH3−CHBr−CH3+AgF⟶CH3−CHF−CH3+AgBr
4. Finkelstein Reaction:
The Finkelstein reaction involves the halogen exchange where an alkyl halide reacts with a halide salt in acetone to form a new alkyl halide. The relevant equation is:
CH3−CH2−Br+Nal ( Acetone) ⟶CH3−CH2−I+NaBr
Now, let's match them:
(A) Sandmeyer
=(S)(B) Fittig
=(P)(C) Swarts = (Q)
(D) Finkelstein
=(R)Therefore, the correct option is:
A=SB=PC=QD=RHence, Option A is the correct answer.
