Elementary Treatment Of Sn1 Sn2 E1 E2 And Radical Reactions

Step 1: Concept
This is a Williamson Ether Synthesis, which follows an mechanism.
Step 2: Analysis
The reagents are a alkyl halide (methyl bromide) and a bulky alkoxide (potassium tert-butoxide).
Step 3: Mechanism
Bulky alkoxides favor elimination ( ) with hindered halides, but since the halide is methyl (least hindered), substitution ( ) occurs to form the ether.
Step 4: Conclusion
The product is tert-butyl methyl ether.
Final Answer:(D)

The correct option is (B): In SN2 reaction
