Haloalkanes and Haloarenes

1. Number of hydrogen atom
   1. monohaloalkane/arene

      Anotações:

      • di-haloalkane, tri-haloalkane also ther monohaloalkanes are divided into 2
      1. sp3 hybrid

         Anotações:

         • single bonds on carbon attached to halogen
         1. Alkyl Halides

            Anotações:

            • R-X, form homologus compounds are Cn H2n+1X
            1. Primary, secondary, tertiary
         2. Allylic Halides

            Anotações:

            • x-c-c=c, 2nd C is allylic carbon. it could be aliphatic or cyclic .
         3. Benzylic Halides

            Anotações:

            • an alkyl halide attached to a benzene ring. this also has primary, 2ary, 3tiary
      2. sp2 hybrid

         Anotações:

         • double bond on c attached to halogen
         1. venylic halide

            Anotações:

            • halogen attached to double bonded carbon of an aliphatic or cyclo alkane
         2. Aryl Halide

            Anotações:

            • X bonded to a C of aromatic ring

Anotações:

• n and iso. o,m,p, sym(metrical) in commom name br comes after propyl. in iupac br first then propane.

1. Alk-ylidene hal-ide

   Anotações:

   • vicinal halide
2. Alk-ylene dihal-ide

   Anotações:

   • germinal halide
3. pg 284

   Anotações:

   • read the table!!!!!

Anotações:

• polarized, carbon partial positive charge, halogen increases down the periodic table bond length increases, Bond enthalpy decreases decreases, dipole moment decreases all cuz F is more electronegative due to its small size

1. B.enthalpy, length, Dipole m.
2. size increase down the group

1. From Alcohols
   1. Cl- ZnCl2
   2. Br- NaBr+H2So4.H
