(a) Interpretation: With help of a chemical test distinguish between cyclohexanone and aniline. Concept Introduction: Cyclohexanone and aniline both are insoluble in water. Distinction between them by a test is based on the fact that cyclohexanone is neutral to both acids and bases while aniline is a weak base and reacts with acid.

Question

17-24 In each pair of compounds, select the one with the higher boiling point. (a) Acetaldehyde or ethanol (b) Acetone or 3-pentanone (c) Butanal or butane (d) Butanone or 2-butanol

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
