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...

What is heterolytic fission? Where one ion gets both electrons from the covalent bond What are produced by heterolytic fission? Ions What is a free radical? An atom or group with an unpaired electron, which is highly reactive as it wishes to pair up this electron What are 3 examples of situations where a free radical can be formed? During thermal cracking, during the reaction of halogens and methane, by homolytic fission What is homolytic fission? A reaction where each atom gets one electron...

I achieved a high A* Grade in my final A-Level exams using these notes!!! I believe you can achieve an A* if you can memorise these notes! Simply use blurting, a method of active recall, to write everything you remember from the notes, then identify the parts you couldn’t remember, then repeat until you can remember it all! If you can do that, you’ve got an A* in the bag! They are clear, concise, and are laid out according to the specification; there is no information missing or in excess...
