Explain how a sample of CH₃CH₂CH₂OH could be distinguished from a sample of CH₃CH₂COOH.

Answers

(a) Add a sample of each to Na₂CO₃ in separate test tubes.
There is effervescence in one with CH₃CH₂COOH but no effervescence in the one with CH₃CH₂CH₂OH.

(b) Add 3 drops of H+/KMnO₄ to a sample of each in a test tube; purple colour is decolourised in CH₃CH₂CH₂OH and purple colour remains in CH₃CH₂COOH.

(c) Add 3 drops of H⁺/K₂Cr₂O₇ to a sample of each in a test tube; in CH₃CH₂CH₂OH, orange colour turns to green but in CH₃CH₂COOH, orange colour is retained.
