- Alcohols and Ethers CI 13.2
- Alcohols
- Having a hydroxyl (-OH) group and have names ending in -ol.
- Naming Alcohols
- Count the number of carbons in the longest chain
- Replace the e at the end of the parent alkane with ol, but retain the e for idol or triol
- Locate the position of the OH group with as low a number as possible.
- Replace the e at the end of the parent alkane with ol, but retain the e for idol or triol
- Count the number of carbons in the longest chain
- Combustion
- Alcohols react completely with oxygen to give carbon dioxide and water.
- Oxygenates
- Alcohols and Ethers are called oxygenates
- Ethers
- Have an alkoxy group (-OR)
- Prefix is the shorter carbon chain
- Oxygenates require less oxygen for complete combustion than the corresponding alkane, since the molecules already have oxygen in them.
- Burn more efficiently than alkanes, producing less CO. They are commonly added to petrol to reduce pollution.
