Is it good to get a negative chromic acid test result when oxidizing cyclododecanol to cyclododecanone? Please explain.
Is it good to get a positive 2,4-DNP test result when oxidizing cyclododecanol to cyclododecanone? Please explain.
Homework Answers
It is good to get negative chromic acid test, as this indicates complete conversion of cyclodocecanol to cyclodocmdecanone.
It’s is good to get 2,4 DNP test positive as this indicates fromation of cyclododecanone from cyclododecanol.

Regarding the qualitative analysis experiment which of the following statements is false? Ellagic acid decolorizes Br_2/CH_2Cl_2 and forms a colorful complex with aqueous FeCl_3. Pulegone reacts positively with 2,4-DNP and Br_2/CH_2Cl_2 reagents. Isoamyl alcohol gives positive NaI/acetone and negative AgNO_3/EtOH tests. Tyrosol reacts positively with Br_2/CH_2Cl_2, and Jones reagents. Umbelliferone gives a positive test with B Br_2/CH_2Cl_2 and negative with 2,4-DNP. Furfural gives positive 2,4-DNP, and Tollen's tests. Which one of the following reagents is not corrosive?
