Transcribed Image Text:The image displays a series of chemical reactions represented by reaction schemes, outlining transformation processes between organic compounds.
**(d)** This section illustrates a chemical reaction where an ethyl acetate (ethyl ethanoate) is transformed into a hydroxy compound containing two benzene rings. The left molecule is shown with an ester group, and the right product is characterized by the addition of an ethyl group and a hydroxyl group between the benzene rings.
**(e)** This part of the diagram shows benzaldehyde (an aldehyde with a benzene ring) being converted into another compound with two benzene rings connected by a carbonyl group. The reaction implies a structural change from an aldehyde group to a ketone.
**(f)** The final section depicts a diketone being converted into an aldehyde compound possessing a benzene ring. The initial structure has two carbonyl groups flanking a methylene group, and the resulting structure contains a simple carbon chain with an aldehyde group attached to the benzene ring.
These reaction schemes demonstrate the transformation of functional groups and the reorganization of molecular structures typical in organic synthesis processes.
