Zusammenfassung der Ressource
Alkene
- Excess O2
- CO2(g) + H2O (l)
- Complete Combustion
- Limited O2
- CO(g) + H2O(l)
- Incomplete Combustion
- H2(g) / Nickel Catalyst
- The double bond is broken.
- Eg: CH3CH=CH2(l) + H2(g) ------> CH3CH2CH3(g)
- Hydrogenation
- Eg: CH3CH=CH2
- Halogen
- Naming goes with "ation" at the end of halogen.
- Eg: Bromination (For the example above)
- Adds 2 halogen atoms removing the C=C bond.
- Eg: CH3CH=CH2 + Br2 -------> CH3CHBrCH2Br
- Electrophillic addition (use of dipole charges and curly arrows)
- H20(l) and CONC: {H3PO4} with HEAT
- Hydration
- Removes the double bond and adds an OH instead
- Eg: CH3CH=CH2 + H20(l) ------> CH3CH(OH)CH3
- Electrophillic addition
- HBr(l)
- Eg: CH3CH=CH2 + HBr -------> CH3CHBrCH3
Anmerkungen:
- Note that HBr breaks down to H+ and Br- .
The H+ always goes to the atom with higher H atoms of the double bond pair.
EG: CH=CH2
The CH2 has more H atoms :)
- Adds a Br and H atom by removing the C=C bond
