The reactions of four organic compounds are given in the table. Which compound could be propan-2-ol?
Areagent/observations: when oxidised with Cr2O7²⁻/H⁺, gives an organic product with a boiling point greater than the original compound: no; when added to ethanoic acid, and a few drops of conc. H2SO4, gives a sweet-smelling compound: no
Breagent/observations: when oxidised with Cr2O7²⁻/H⁺, gives an organic product with a boiling point greater than the original compound: no; when added to ethanoic acid, and a few drops of conc. H2SO4, gives a sweet-smelling compound: yes
Creagent/observations: when oxidised with Cr2O7²⁻/H⁺, gives an organic product with a boiling point greater than the original compound: yes; when added to ethanoic acid, and a few drops of conc. H2SO4, gives a sweet-smelling compound: no
Dreagent/observations: when oxidised with Cr2O7²⁻/H⁺, gives an organic product with a boiling point greater than the original compound: yes; when added to ethanoic acid, and a few drops of conc. H2SO4, gives a sweet-smelling compound: yes
✓ Correct answer
B: reagent/observations: when oxidised with Cr2O7²⁻/H⁺, gives an organic product with a boiling point greater than the original compound: no; when added to ethanoic acid, and a few drops of conc. H2SO4, gives a sweet-smelling compound: yes
