Advices For Studying Organic Chemistry

8. D:

1 by using the two electons of the π bond to
the carbon atoms ⇒ leaves a vacant p orbital and a +
ion of a carbocation and a halide ion:

1B THE MECHANISM OF THE ADDITION OF HX TO A DOUBLE BON

. The H+ of HX reacts with the alkene
form a σ bond to one of
charge on the other carbon ⇒ format
2. The carbocation is highly reactive and combines with the halide ion:


8.1C ELECTROPHILES ARE LEWIS ACIDS:

ewis acids.


  1. Nucleophiles: molecules or ions that can furnish an electron pair ⇒ Lewis bases.

  2. Any reaction of an electrophile also involves a nucleophile.

  3. In the protonation of an alkene:

    1. The electrophile is the proton donated by an acid.

    2. The nucleophile is the alkene.



  4. Electrophiles: molecules or ions that can accept an electron pair ⇒ L
