This problem is asking for the ketone that will be formed when an specific alcohol is oxidized with chromic acid. Although there is no attached file or molecule, you should select the secondary alcohol.
In organic chemistry, oxidation reactions such as those producing aldehydes and carboxylic acids from primary alcohols and those producing ketones from secondary alcohols are based on either the increase of oxygen atoms or the decrease of hydrogen atoms in the molecule.
However, primary carbons are those having one bond with another carbon atom, and they lead to the formation of aldehydes and carboxylic acids as shown below:
[tex]R-CH_2-OH\rightarrow R-HC=O\rightarrow R-C(=O)-OH[/tex]
On the other hand, secondary alcohols are those having the OH at a carbon with two bonds with two different carbon atoms and lead to formation of ketones upon the oxidation with chromic acid:
[tex]R_1-CH(OH)-R_2\rightarrow R_1-C(=O)-R_2[/tex]
In such a way, you must select the secondary alcohol for your answer, regardless not included in the question you shared.
