### Image Description This image displays the molecular structures of three organic compounds, numbered 1 to 3. 1. **Structure 1:** - This molecule is a phenylbutane derivative. It consists of a benzene ring (a hexagonal ring with alternating double bonds) attached to a butane moiety. The butane section includes chiral carbon indicated with wedges, suggesting stereochemistry. 2. **Structure 2:** - This molecule is a para-hydroxyacetanilide. It features a benzene ring with a hydroxyl group (OH) on the para position and an amide group (NH) connected to an acetic acid group (CO). 3. **Structure 3:** - This molecule is a methoxyacetophenone. It has a benzene ring with a methoxy group (OCH3) attached to it and a carbonyl group (C=O) bonded directly to the ring. These structures illustrate different functional groups and configurations commonly studied in organic chemistry, highlighting concepts such as aromatic chemistry, stereochemistry, and functional group identification.
