Question

14. Which of the following compounds would not turn chromic acid from orange to green? OH H3C-C-c-OH OH A. C. 15. You have examined several groups of substances in the laboratory. The following table includes nformation regarding solubility in water and results of specific tests for functional groups. Use it to identify unknowns A,B,C,D,E,F, and G. (Determine with unknown from the list below belongs to which letter) Unknown sol/H0 Chromic 2,4 Tollens FeCls 2KI Br2 Lucas Acid green ppt NR green ppt NR E. NR G. NR Positive (+) reaction with: 2,4,DNP forms yellow or red precipitate (ppt). Tollens forms silver mirror FeCl deep purple color 2KI (iodoform test) yellow precipitate (ppt). -red color of bromine disappears Lucas- rapid formation of a cloudy precipitate (ppt). Negative reaction is indicated by (-) or NR (no reaction) Water solubility: (+) indicates soluble in water, (-) indicates not soluble in water. Unknowns include: acetone, cyclohexene, ethanol, formaldehyde, hexane, phenol, and tert-butyl alcohol (2methyl, 2propanol)

Explanation / Answer

14) C is a tertiary alcohol which is not oxidized by chromic acid and hence chromic acid doesnt change it's colour to green( this colour change is normally due to recution of Cr6+ to Cr 3+ which occurs when the alcohol is oxidised
