Complete the reaction schemes below providing the reagents required to achieve the
transformation. More than one step may be necessary for each scheme.

 

The image presents three chemical reactions involving organic compounds, each represented visually with structural formulas.

1. **First Reaction:**

   - **Reactant:** The starting compound on the left is `(CH3)2CHCH2OH` (a primary alcohol with a phenyl group, also written as Ph).
   - **Product:** The product on the right is `(CH3)2CH(OH)CH2Ph` (a phenyl-substituted secondary alcohol). The reaction involves the change in the position of the hydroxyl group, moving from a primary to a secondary carbon.

2. **Second Reaction:**

   - **Reactant:** The reactant on the left is `CH3CH2CH2OH` (propanol, a primary alcohol).
   - **Product:** The product is `(CH3)2CHCH2OH` (a secondary alcohol, 2-butanol). This conversion may involve a methyl shift to generate the secondary alcohol.

3. **Third Reaction:**

   - **Reactant:** The compound is `CH3CH2COOH` (propanoic acid, a carboxylic acid).
   - **Product:** The product is `CH3CH2COCH3` (a ketone, specifically butanone). The carboxylic acid is transformed into a ketone, possibly through a decarboxylation step followed by an addition.

Each of these transformations includes an arrow indicating the direction of the chemical reaction from reactants to products. These represent typical organic chemistry reactions involving rearrangements and group transformations.
