Electrophilic Addition Mechanism

The source states that the characteristic reaction of alkene and alkyne is electrophilic addition.

Step 1
C=C+E+⟶carbocationC=C+E^+\longrightarrow\text{carbocation}
Step 2
carbocation+Nu:⟶addition product\text{carbocation}+Nu: \longrightarrow \text{addition product}
electrophilic addition
C=C + E+C-C+C-C+ + Nu:C-CEENu+ on more substituted carbon

Notes

  • In the source mechanism, the positive charge is on the more substituted carbon.
