Match List I (Reaction) with List II (Reagent) and select the correct answer using the codes given below the lists:
Options
- A\mathrm{I}\mathrm{II}\mathrm{III}
- B\mathrm{I}\mathrm{II}\mathrm{III}
- C\mathrm{I}\mathrm{II}\mathrm{III}
- D\mathrm{I}\mathrm{II}\mathrm{III}
Correct answer
C. \mathrm{I}\mathrm{II}\mathrm{III}
Step-by-step solution
I. Etard reaction: This reaction converts toluene into benzaldehyde using C. Chromyl chloride as the reagent.
II. Hydroxylation: The hydroxylation of an alkene to a vicinal diol is a common reaction. A reagent used for this is cold, dilute, alkaline D. (\mathrm{KMnO}_4) (Baeyer's reagent).
III. Dehydrohalogenation: This is an elimination reaction where a hydrogen halide is removed from an alkyl halide to form an alkene. It typically requires a strong base like A. Alcoholic KOH.
IV. Friedel-Crafts reaction: This is an electrophilic aromatic substitution reaction. It requires a Lewis acid catalyst such as B. Anhydrous (\mathrm{AlCl}_3).
Therefore, the correct matches are I-C, II-D, III-A, IV-B, which corresponds to option (3).
