Resource summary

Haloalkanes and Haloarenes
1 Classification
1.1 Number of hydrogen atom
1.1.1 monohaloalkane/arene

Annotations:

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

Annotations:

  • single bonds on carbon attached to halogen
1.1.1.1.1 Alkyl Halides

Annotations:

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

Annotations:

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

Annotations:

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

Annotations:

  • double bond on c attached to halogen
1.1.1.2.1 venylic halide

Annotations:

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

Annotations:

  • X bonded to a C of aromatic ring
2 Nomenclature

Annotations:

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

Annotations:

  • vicinal halide
2.2 Alk-ylene dihal-ide

Annotations:

  • germinal halide
2.3 pg 284

Annotations:

  • read the table!!!!!
3 Bond nature

Annotations:

  • 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
3.1 B.enthalpy, length, Dipole m.
3.2 size increase down the group
4 Method of preparation
4.1 From Alcohols
4.1.1 Cl- ZnCl2
4.1.2 Br- NaBr+H2So4.H
