Answer 2

The product formed in the Wittig reaction with formaldehyde will be a terminal alkene.

• Wittig reaction involves the formation of alkenes from aldehydes or ketones. The reagent used is triphenyl phosphonium ylide.
• The reaction is as follows:

$H_{2} C=O + H_{2} C=P- PH_{3}$ → $CH_{2} = CH_{2} + PH_{3}P=O$

• Thus, the product formed is ethene, an alkene.
