Williamson synthesis is an example of:
Show Hint
- Nucleophilic addition reaction
- Electrophilic substitution reaction
- Nucleophilic substitution reaction
- Electrophilic addition reaction
The Correct Option is C
Solution and Explanation
Williamson synthesis is the industrial and laboratory method for preparing ethers.
Step 2: Analysis
In this reaction, a sodium alkoxide ($R-O^-Na^+$) reacts with an alkyl halide ($R'-X$). The alkoxide ion ($R-O^-$) is a strong nucleophile that attacks the electrophilic carbon bearing the halogen. The halide ion is displaced as a leaving group.
Step 3: Conclusion
This is a classic $S_N2$ mechanism -- a nucleophilic species substitutes a leaving group -- making it a nucleophilic substitution reaction. The reaction: $R-ONa + R'-X \rightarrow R-O-R' + NaX$.
Final Answer: (C)
