Question

An organic compound a having the molecular formula c3h8o is a liquid at room temperature. the organic liquid a reacts with sodium metal to evolve a gas which burns causing a little explosion. when the organic liquid a is heated with concentrated sulphuric acid at 170°c, it forms a compound b which decolourises bromine water. the compound b adds one molecule of hydrogen in the presence of ni as a catalyst to form compound c which gives substitution reactions with chlorine

Answer 1

Hi, please consider the answers given below;

1. Compound A is propanol which reacts with sodium metal with the evolution of hydrogen gas and this is the gas which is causing little explosion. Propanol is normally liquid at room temperature.

2. Compound B is propene since it decolourises bromine water. This reaction is normally an addition reaction.

3. Compound C is propane since it gives a substitution reaction with chlorine.
