- Alkanes, Alkenes, Alcohols
- alkANEs
- CnH2n+2
- Reactions
- Substitution with halogens: UV
- CH4 + Br2--->CH3Br + HBr
- Cracking : turning long alkane chains into smaller ones
- Aluminium oxide
- 600-700 C
- Substitution with halogens: UV
- alkANEs
- CnH2n
- Reactions
- Addition of Halogens : starts with an alkene, but when reacts with bromine (Br) the double bonds break = alkane (orange to colourless)
- C2H4 + Br2 = C2H4Br2
- Hydration of ethene
- Phosphoric acid
- 300 C
- 60-70 atm
- C2H4 + H2O = C2H5OH (ethanol)
- Fermentation
- Glucose + water = ethanol + C02
- Anaerobic condition
- 30-40 C
- Addition of Halogens : starts with an alkene, but when reacts with bromine (Br) the double bonds break = alkane (orange to colourless)
- Alcohols
- Reactions
- Dehydration of ethanol
- Aluminium oxide
- Ethanol back to ethene and water
- Fermentation
- Glucose + water = ethanol + C02
- Anaerobic condition
- 30-40 C
- Dehydration of ethanol
- Reactions
- alkANEs
