Question

Match the following: 

 

• A. A-III, B-IV, C-II, D-I
• B. A-III, B-IV, C-I, D-II
• C. A-II, B-III, C-I, D-IV
• D. A-I, B-II, C-IV, D-III

Hint:

Aryl halides have halogens directly on the aromatic ring, while benzyl halides have halogens on the side chain (CH\textsubscript{2} group).

Answer 1

The Correct Option is B

Step 1: Understand the halide types. Vinyl halide: Halogen attached to an alkene carbon (double bonded) — matches III. 
Allyl halide: Halogen attached to a carbon next to a double bond — matches IV. 
Benzyl halide: Halogen attached to a CH₂ group next to a benzene ring — matches I. 
Aryl halide: Halogen directly bonded to the benzene ring — matches II. 
Step 2: Match accordingly: \[ \begin{aligned} A (\text{Vinyl}) &\rightarrow \text{III} \\ B (\text{Allyl}) &\rightarrow \text{IV} \\ C (\text{Benzyl}) &\rightarrow \text{I} \\ D (\text{Aryl}) &\rightarrow \text{II} \end{aligned} \]
