What would you predict for the reactivity of a chlorine directly on the double bond of an alkene?
Thepotemich [5.8K]

Prediction for the reactivity of a chlorine directly on the double bond of an alkene would be in the following:

A dipole is created in the halogen molecule as the non-polar chlorine molecule approaches the alkene double bond.

A chloride ion is produced when the pi link in the alkene double bond breaks and establishes a bond with the delta positive Cl atom.

The chloride ion undergoes carbocation as a result, and along with the carbocation, a single electron pair forms a dative bond.

Carbon double bonds are more powerful and compact than single bonds. The number of bonds is two.

Additionally, double bonds have a lot of electrons, which could make them more reactive in the presence of a powerful electron acceptor.
