Chemistry - Carbonyl compounds Question with Solution | TestHub

Question Explanation:

Identifying starting materials for Wittig reaction synthesis.

Concept:

Wittig Reaction

Solution:

The Wittig reaction converts a carbonyl (C=O) into an alkene (C=C) using a phosphorus ylide. 3 The ylide is prepared from an alkyl halide (A) + Ph₃P + base. The ylide then reacts with a carbonyl compound (B). To form the product (Ethylidenecyclohexane), we can split the double bond: Route 1: Cyclohexyl halide (A) and Acetaldehyde (B).

Route 2: Ethyl halide (A) and Cyclohexanone (B). Both options 1 and 2 provide the correct fragments to form the final alkene.
