Answer #1

1. Only first option is correct, chromium trioxide with sulphuric acid forms a catalyst known as jones reagent and it is useful for oxidation of primary alcohol and aldehydes to carboxylic acids and secodary alcohol to ketones.

2. primary alcohol with PCC(Pyridinium chlorochromate) oxidized to aldehydes, but when used with DMF it furthere oxidize the compound to carboxylic acid.

3. Cleavage of alkene with ozone in presence of DSM(dimethyl sulphide) produces carbonyl compounds.

4. Reduction of ester with DIBAL yields the aldehydes.
