An unknown substance had a positive reaction with 2,4-DNP test. The unknown reacted like a secondary alcohol with the Lucas reagent. It was negative with the Iodoform and Benedict's test. What possible functional groups does the unknown contain? -primary alcohol -secondary alcohol -tertiary alcohol -ketone -aldehyde -methyl -none tested I answered ketone and aldehyde. I did not receive full credit. I also answered secondary, tertiary, ketone, and acetone, but did not receive full credit.
