| + | In general, SN1 substitution can take place when a stable carbocation can be formed. If not, the reaction follows the SN2 mechanism. | ||
| + | The SN1 <jmol><jmolLink><script>anim mode once; frame range 1 10; delay 0.5; frame play</script><text>reaction starts</text></jmolLink></jmol> with the removement of a hydroxide-ion out of the molecule, in this case tert-Butanol. By this, a positively charged carbocation with a planar geometry is formed. This step is also the rate-determing step because it is the slowest step in this reaction. | ||
| + | In the <jmol><jmolLink><script>anim mode once; frame range 11 20; delay 0.5; frame play</script><text>second step</text></jmolLink></jmol>, the haloanion bound to the carbocation, and a neutral haloalkane is formed. With this step, the hydroxy-substituent is replaced by a halogen-substituent. | ||
