Alkane to halogenoalkane - Study guides, Class notes & Summaries

Thermal Cracking - correct answer - High temperatures (1000C) - High pressure (up to 70atm) - Produces ALKENES - E.g. ethene --> polyethene Catalytic Cracking - correct answer - Zeolite catalyst - Slight pressure - High temperature (450C) - Produces AROMATICS Reformation - correct answer Alkanes --> cycloalkanes/ aromatic hydrocarbons - Straight chain alkanes are a lot more likely to...

Hydrocarbons - Answer Covalent compounds containing only hydrogen and carbon atoms Alkanes - Answer Saturated Hydrocarbons Alkenes - Answer Unsaturated hydrocarbons containing a double bond. Unsaturated Hydrocarbon Test - Answer Add hydrocarbon to bromine water. Colour goes from brown to colourless. Addition of Hydrogen - Answer Alkene + Hydrogen → Alkane. Requires temperature of 150°C and a Pt or Ni catalyst. Addition of Halogen - Answer Alkene + Halogen (e.g. Bro...
