In the following sequence of reaction, the major products B and C respectively are :
The Correct Option is A
Approach Solution - 1
To solve this sequence of reactions, let's analyze each step:
- First Reaction:
The substrate is a cyclic compound with chlorine and bromine substituents. It reacts with sodium (Na) in the presence of diethyl ether (Et2O), which is typically used for a Wurtz reaction. This reaction will form an intermediate where two halogen atoms are removed, and a new carbon-carbon bond is formed, resulting in a ring structure with two additional carbon atoms.
- Second Reaction:
The intermediate compound A is then treated with magnesium (Mg) in diethyl ether to form a Grignard reagent. The Grignard reagent is represented as RMgX where R is the organic group.
- Third Reaction:
The Grignard reagent reacts with D2O (deuterium oxide) to replace the MgBr part with a deuterium atom (D), resulting in compound B, which is a deuterated hydrocarbon.
- Fourth Reaction:
The compound A also reacts simultaneously via CoF2-catalyzed reaction to form compound C. CoF2 is used as a catalyst in some polymerization reactions, hinting that a new product formation may involve a fluorinated derivative or similar activity.
The reactions above indicate that compound B is the deuterated cyclopropane and compound C may involve some modifications due to CoF2. Based on the given options and the typical reactivities, the product matches the structure described by:
Thus, the major products B and C are identified as the ones shown in the correct answer option above.
