Draw the appropriate reagents/ solvent above and below the arrow necessary to conduct the following reactions.

### Chemistry Transformations #### Reaction Schemes ##### b) **Starting Material:** - An aromatic benzene ring bonded to a carbon with a three-bond side chain ending in a triple bond (an alkyne). **Transformation:** - An arrow pointing to the product. **Product:** - An aromatic benzene ring bonded to a carbon with a two-bond side chain ending in a carbonyl group (a ketone). **Representation:** - The transformation suggests an oxidation or a rearrangement converting an alkyne side chain into a ketone functional group attached to the benzene ring. ##### c) **Starting Material:** - An aromatic benzene ring bonded to a carbon with a three-bond side chain ending in a triple bond (an alkyne). **Transformation:** - An arrow pointing to the product. **Product:** - An aromatic benzene ring bonded to a carbon with a two-bond side chain ending in a carbonyl group (an aldehyde). **Representation:** - The diagram suggests an oxidation or rearrangement converting an alkyne side chain into an aldehyde functional group attached to the benzene ring. These transformations are commonly seen in organic chemistry, where functional groups attached to aromatic rings undergo various reactions to form different functional groups. The reactions exemplify the versatility in modifying the chemical structure of hydrocarbons to yield specific compounds with desired chemical functionalities.

**Transformation of Chemical Compounds** In this example, we observe a chemical reaction that transforms one organic compound into another. **Explanation of Diagrams:** **Diagram (a):** - **Reactant (Left):** The molecule on the left side of the arrow is the starting material for the reaction. It is a benzyl compound, featuring a benzene ring (a hexagon with alternating double and single bonds) attached to a carbon chain. This chain has two chlorine atoms attached at different positions. Specifically, the structure includes a benzene ring bonded to a carbon (CH) group, which in turn is bonded to a CH2 group possessing a chlorine (Cl) atom. - **Product (Right):** The molecule on the right side of the arrow represents the product. This structure shows the benzene ring bonded to a carbon which is connected to another carbon-carbon triple bond, forming a propyne group (a three-carbon chain with a terminal triple bond). **Reaction Overview:** This reaction transforms the starting material (a benzyl chloride derivative) into a final product where the aliphatic chain with chlorine atoms is converted into an alkyne group (a carbon-carbon triple bond). **Detailed Chemical Transformations:** - The initial reactant is a chlorinated toluene derivative. - The transformation likely involves several steps: the removal of chlorine atoms, formation of double bonds, and finally the creation of a triple bond, converting the side chain into a propyne group. This type of reaction could involve dehydrohalogenation steps and/or possible use of strong bases to remove the hydrochloric acid by-products, converting the chlorinated compound into an alkyne derivative. Understanding such chemical transformations is crucial in organic synthesis, allowing chemists to build complex molecules from simpler ones by manipulating functional groups and bonds.
