Solution
The correct option is C
CrO3−H2SO4 is the Jones reagent, it will oxidise primary alcohol to carboxylic acid and secondary alcohol to ketones.
Wacker process:
Oxidation of ethylene to acetaldehyde in the presence of palladium(II) chloride as the catalyst.
When the vapour of ethanol is passed over heated copper catalyst at 573 K , it is dehydrogenated to acetaldehyde.
Di-isobutyl aluminum hydride or DIBAL-H has been used to reduce nitriles and esters into aldehydes.
Hence, option (a) is correct.
