- Addition Reaction
- Is one in which two substances react together to form a single substance
- Example of an Addition Reaction
- Ethene + Hydrogen = Ethane
- Double bond broken
- Ethene + Hydrogen = Ethane
- Mechanism of reaction between ethene and bromine
- Step 1.
- High conc. of negative charge in the C double bond C, causes the Br - Br bond to become POLARISED
- Step 2.
- Heterolytic Fission of Bromine due to polarisation being so great
- Step 3.
- CARBONIUM ION - Bridged structure exists within Bromine
- Step 4.
- Attack on the carbonium ion by bromide ion (Br-).
- Evidence of Ionic Addition
- Ethene reacting with water and NaCl
- PRODUCTS FORMED- 1-bromo-2-chloroethane,2-bromoethanol
- Ethene reacting with water and NaCl
- Step 1.
- Have to know mechanisms for
- Ethene and Chlorine
- Ethene and HCl
- Ethene and Chlorine
- Polymerisation Reactions
- Ethene and ethene
