Which of the following compound is formed when NaCl reacts with CH3MgBr?
- A
CH3CN
- B
CH3Na
- C
CH3CH2NH2
- D
None of these
The reaction of NaCl (sodium chloride) with CH₃MgBr (methylmagnesium bromide, a Grignard reagent) does not occur under normal conditions. Sodium chloride is a stable, neutral salt that does not provide a suitable site for a Grignard reaction. Grignard reagents typically react with carbonyl compounds, alkyl halides (under specific conditions), and other electrophilic sites, but not with neutral salts like NaCl. Thus, none of the given products can be formed from this reaction.
This option is incorrect. Sodium chloride and methylmagnesium bromide do not react to form acetonitrile.
This option is incorrect. There is no formation of methyl sodium in the reaction between NaCl and CH₃MgBr.
This option is incorrect. Ethylamine is not a product of the reaction between NaCl and CH₃MgBr.
Correct. No reaction occurs between NaCl and CH₃MgBr under normal conditions because NaCl is a neutral salt and methylmagnesium bromide, a Grignard reagent, does not react with it directly.
