C2 4.1 How Fast?
Meredith Fletcher
Alkene
1 Excess O2
1.1 CO2(g) + H2O (l)
1.2 Complete Combustion
2 Limited O2
2.1 CO(g) + H2O(l)
2.2 Incomplete Combustion
3 H2(g) / Nickel Catalyst
3.1 The double bond is broken.
3.1.1 Eg: CH3CH=CH2(l) + H2(g) ------> CH3CH2CH3(g)
3.2 Hydrogenation
4 Eg: CH3CH=CH2
5 Halogen
5.1 Naming goes with "ation" at the end of halogen.
5.1.1 Eg: Bromination (For the example above)
5.2 Adds 2 halogen atoms removing the C=C bond.
5.2.1 Eg: CH3CH=CH2 + Br2 -------> CH3CHBrCH2Br
6 H20(l) and CONC: {H3PO4} with HEAT
6.1 Hydration
6.2 Removes the double bond and adds an OH instead
6.2.1 Eg: CH3CH=CH2 + H20(l) ------> CH3CH(OH)CH3
7 HBr(l)
7.1 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 :)
7.2 Adds a Br and H atom by removing the C=C bond
