(b) An organic compound has the molecular formula C5H100. Thecompound does not reduce Tollen's reagent, but reacts with Brady'sreagent to give orange precipitate. On vigorous oxidation, the molecuteproduces ethanoic acid and propanoic acid. The compound also givesiodoform test. Identify the compound and write equations for chemicalreactions involved.3 |

Answer» A does not reduce Tollen's reagent. So it must be a ketone. Since it answers Iodoform test, it must be a methyl ketone (i.e. containing CH3CO- group). So, according to formula, compound A must be CH3COCH2CH2CH3. This implies B must be CH3CH2COOH, and C must be CH3CH2CH2CH3(remember that the Kolbe's electrolysis gives an alkane having twice the no. of carbon atoms as in the carboxylate salt). |
