Alkene

Alkene

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