Concept:Oxidation of secondary alcohols produces ketones; propanone is a ketone.Explanation:Propanone has the structure CH3​COCH3​.It is a ketone, which is obtained by the oxidation of a secondary alcohol.2-Propanol is a secondary alcohol with the structure CH3​CH(OH)CH3​.The −OH group is attached to the middle carbon atom.On oxidation, 2-propanol forms propanone:CH3​CH(OH)CH3​[O]​CH3​COCH3​+H2​O1-Propanol is a primary alcohol and gives propanal or propanoic acid.2-Butanol is a secondary alcohol but gives butanone, not propanone.2-Methylbutan-1-ol is a primary alcohol and does not form propanone.Answer:Option B: 2-Propanol
