When methl iodide and ethyl iodide are treated with sodium metal possible major products are obtained ?
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
In the Wurtz reaction, methyl iodide and ethyl iodide couple in three ways: methyl with methyl gives ethane, methyl with ethyl gives propane, and ethyl with ethyl gives butane. Therefore, 3 possible major hydrocarbon products are formed. The likely mistake is choosing 2 by counting only the two symmetrical products and forgetting the cross-coupled product.

About Nucleophilic Substitution
Nucleophilic substitution replaces a leaving group in an alkyl halide when an electron-rich nucleophile attacks the carbon atom. The topic compares SN1 and SN2 mechanisms, including reaction conditions, substrate structure, solvent effects, nucleophile strength, carbocation formation and stereochemical changes, and distinguishes substitution from elimination.
