(A) CH₃MgBr
(B) CH₃Br
(C) CH₃Cl
(D) CH₄
Choose the correct answer from the options given below:

• A. (B), (A), (D), (C)
• B. (A), (C), (B), (D)
• C. (B), (A), (C), (D)
• D. (C), (B), (D), (A)

Answer 1

The Correct Option is C

This question requires analyzing the sequential progression of organic compounds within a chemical reaction, specifically focusing on the formation and subsequent reactions of a Grignard reagent. The process is detailed below:

1. Grignard Reagent Synthesis:
   Initially, an alkyl halide reacts with magnesium in anhydrous ether to produce a Grignard reagent. The standard alkyl halide employed is (B) CH₃Br. Therefore, (B) CH₃Br reacts with magnesium to form (A) CH₃MgBr.
2. Grignard Reagent Nucleophilic Attack:
   Subsequently, the Grignard reagent (A) CH₃MgBr functions as a nucleophile, capable of attacking electrophilic centers. In this context, the target molecule, (C) CH₃Cl, acts as an electrophile, typically to generate a hydrocarbon.
3. Final Product Generation:
   The reaction between Grignard reagent (A) and halomethane (C), followed by hydrolysis, results in the final product, (D) CH₄.

Based on established chemical reactivity and the typical Grignard reaction pathway, the required sequence is (B), (A), (C), (D).
