Answer 1

I. physical state- viscous liquid

color-colorless

odour-sweet characteristic odour

II. It is soluble in water but much denser than it, therefore it sinks when mixed with water.

III. Tollen's-

Result-no silver mirror appears

Conclusion-negative test. The compound is not an aldehyde but a ketone

Iodoform-

Result-yellow ppt appears

Conclusion-positive test. There is at least one methyl group attached to a carbonyl carbon in the compound.

IV. We now know that the compound is a carbonyl compound with a methyl group attached to the carbonyl carbon. It is a ketone.
