Kiko, a Chem 31.1 student, accidentally shuffled two test tubes with different compounds on hisway to the laboratory. To confirm the possible identities of the compounds, Kiko added neutralKMNO4 and Lucas reagents to both test tubes labeled A and B. Test tube A gave a brown precipitatein neutral KMNO4 while test tube B produced a purple solution in the same test. Upon subjectingto Lucas Test, both test tubes produced layers. Which of the following are the possible identities ofthe compounds A and B?A. Sec-butanol and 3-methyl-3-pentanolB. n-propanol and tert-butanolC. isopropyl alcohol and 4-nitrophenolD. hexanol and cyclopentanolENTAL
