Question

Identify the type of the following reaction?

• A. Williamson synthesis
• B. Gattermann-koch reaction
• C. Williamson continuous etherification process
• D. Etard reaction

Hint:

An alkoxide reacting with an alkyl halide to form an ether is the Williamson synthesis.

Answer 1

The Correct Option is A

Step 1: Recognise the pattern
Alkoxide ion plus alkyl halide gives an ether by nucleophilic substitution.

Step 2: Eliminate
Gattermann-Koch and Etard reactions give aromatic aldehydes, so (B) and (D) are out.
The continuous process starts from an alcohol and acid, not from a halide, so (C) is out.

Step 3: Final check
An alkoxide plus an alkyl halide giving an ether is the Williamson synthesis, so (A) is the answer.

Final Answer:
Option (A), Williamson synthesis, is correct. \[ \boxed{\text{(A) }\text{Williamson synthesis}} \]
