Ethanol- chemistry

Adjunto:

• Ethanol

1. Melting point - 156K
   1. Boiling point - 351K
2. Soluble in water
3. Used in medicines
   1. EG ; Tinchure iodine, cough syrups & many tonics
4. Liquid at room temperature
5. CH3CH2OH - Chemical formula
6. Reaction of Ethanol with Sodium 2Na + 2Ch3Ch2OH 2Ch3Ch2ONa + H2O Alcohols react with Sodium leading to the evolution of Hydrogen. With Ethanol , The other product is Sodium Ethoxide
7. Consumption in  Small quantities- Causes drunkness  Large quantities- lead to health problems
8. Reaction to give unsaturated hydrocarbons: Heating ethanol at 443K with excess concentrated sulphuric acid results in the dehydration of ethanol to give ethene-CH3 CH2OH gives CH2=CH2+Water The concentrated sulphuric acid can be regarded as dehydrating agent which removes water from ethanol
