When bromine water is added to an alkene, the brown color of the bromine water disappears, indicating that the alkene undergoes addition reaction with bromine (forming a dihaloalkane). Related Questions: Give three examples of unsaturated hydrocarbons. Draw electron dot and cross structure for ethene. How can you differentiate ethane from ethene? What do you mean … Read more
Alkynes are more reactive than alkanes because they contain a triple bond, which is less stable and more prone to attack by reagents. Alkanes, on the other hand, have single bonds, which are more stable Related Questions: Give three examples of unsaturated hydrocarbons. How can you differentiate ethane from ethene? What do you mean by … Read more
Saturated hydrocarbons have only single bonds between carbon atoms (e.g., alkanes), whereas unsaturated hydrocarbons have double or triple bonds between carbon atoms (e.g., alkenes and alkynes). Related Questions: Give three examples of unsaturated hydrocarbons. How can you differentiate ethane from ethene? What do you mean by dehydration reaction? Give one example. Draw structural formulas … Read more
Ethene can be prepared from ethanol by dehydration. In the presence of concentrated sulfuric acid (H₂SO₄), ethanol (C₂H₅OH) undergoes dehydration to form ethene (C₂H₄) and water (H₂O). Equation: C₂H₅OH → C₂H₄ + H₂O Related Questions: Give three examples of unsaturated hydrocarbons. How can you differentiate ethane from ethene? What do you mean by dehydration reaction? … Read more
