A multi-step synthesis of 1-penten-3-ol using acetylene as only source of carbon atoms has to be given. Concept Introduction: Catalytic hydrogenation: It is the addition of molecular hydrogen across triple bond in presence of Lindlar’s catalyst. This catalyst stops hydrogenation to alkene . Ozonolysis: It involves breaking of alkene double bond and addition of oxygen atoms to form carbonyl compounds. Hydro-halogenation reaction: In this reaction, hydrogen halide added across the unsaturated bond (alkene). Markovnikov’s rule: An unsymmetrical alkene reacts with hydrogen halide in which halide ions goes to the more substitution position of carbon-carbon double bond which provides alkyl halides.
