Halogenoalkanes Study guides, Class notes & Summaries

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 el...

AQA AS Organic Chemistry exam questions with 100% correct answers Define the term 'empirical formula' - ANSWERS A formula that gives the simplist whole number ration of atoms of each element in a compound Define the term 'molecular formula' - ANSWERS A way of representing molecules that shows the actual number of atoms of each element in a molecule Define the term 'General formula' - ANSWERS An algebraic formula that can describe any member of a family of compounds Define the t...

Edexcel A Level Chemistry Paper 3 Mark Scheme June Why does infrared spectroscopy work? - ANS-All bonds vibrate at a characteristic frequency when exposed to infrared radiation Steps in free radical substitution - ANS-Initiation (producing free radicals), Propagation (form products and more free radicals) and Termination (removing free radicals by forming molecules) Example of free radical substitution - ANS-Chlorine, methane and UV light Which carbocation intermediate is the mos...

All criteria achieved distinction P1, M1, M2, D1.

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...
