Alcohols • All have an OH or Hydoxyl group
Alcohol: Ethanol This is the structure of ethanol. What is its key feature that makes it an alcohol
Methanol • What do you think the formula of methanol will be? • What is the molecular formula for simple organic alcohols? This is a picture of a meths drinker. Methylated spirit is ethanol laced with methanol . Methanol is added so that undiluted ethanol can be sold without the large amount of tax present in strong spirits. The only problem is the meths drinkers drink the spirit and the effects of methanol do not wear off. They are permanently brain damaged.
Alcohols • Alcohols are part of a large group of carbon chemical families that contain oxygen. Ones we are going to study are: • Alcohols ROH • Ethers ROR’ • Aldehydes RC=OH • Ketones RC=OR • Carboxylic acids RC=OOH • (where R stands for the carbon chain and C=O stands for carbon bound to oxygen by a double bond)
