The specific chemical reactions for List-I are missing from the provided text. Therefore, an exact match cannot be determined. However, the reagents given in List-II are standard reagents used in organic chemistry: $CrO_3$ is used for the oxidation of primary alcohols to aldehydes or secondary alcohols to ketones; alkaline $KMnO_4$ followed by heating is a strong oxidizing agent used to convert alkylbenzenes to benzoic acid or vigorously oxidize primary alcohols; and $O_3$ followed by $Zn/H_2O$ is used for the reductive ozonolysis of alkenes to yield aldehydes and/or ketones.
