Four compounds have the formula C4H8O, identify possible compounds.
Four compounds have the formula C4H8O. Identify possible compounds (by name or structure). Compounds A and C have similar boiling points; Compounds B and D have significantly lower boiling points than A and C.
A Reacts with oxidizing agents; reacts immediately with bromine; negative Iodoform Test; negative Lucas Test.
B Negative result with oxidizing agents; reacts with bromine only with uv-light; negative Iodoform test; as previously mentioned, has relatively low boiling point.
C Reacts with oxidizing agents; reacts immediately with bromine; gives a positive result to Lucas Test after 8 minutes; shows yellow precipitate result in Iodoform Test
D No reaction with oxidizers; reacts with bromine only when uv-light is present; has positive Iodoform test.
Solution Preview
C4H8O -> Compounds can be aldehyde, ketone, ether, and alcohol
-> Double bond(C=C) or ring or C=O bond
Lucas test = (+) -> secondary or tertiary alcohol
Lodoform test = (+) -> methyl ketone, secondary alcohol(R-CH(OH)-CH3)
A -> Reacts with oxidizing agents -> NOT ketone, ether, or tertiary alcohol
-> Reacts immediately with bromine ? Double bond(C=C)? NOT aldehyde
-> Negative Iodoform Test ? NOT secondary ...
