Haloalkanes and Haloarenes
- Classification
- Number of hydrogen atom
- monohaloalkane/arene
Anmerkungen:
- di-haloalkane, tri-haloalkane also ther
monohaloalkanes are divided into 2
- sp3 hybrid
Anmerkungen:
- single bonds on carbon attached to halogen
- Alkyl Halides
Anmerkungen:
- R-X, form homologus compounds are Cn H2n+1X
- Primary, secondary, tertiary
- Allylic Halides
Anmerkungen:
- x-c-c=c, 2nd C is allylic carbon. it could be aliphatic or cyclic .
- Benzylic Halides
Anmerkungen:
- an alkyl halide attached to a benzene ring.
this also has primary, 2ary, 3tiary
- sp2
hybrid
Anmerkungen:
- double bond on c attached to halogen
- venylic halide
Anmerkungen:
- halogen attached to double bonded carbon of an aliphatic or cyclo alkane
- Aryl Halide
Anmerkungen:
- X bonded to a C of aromatic ring
- Nomenclature
Anmerkungen:
- n and iso. o,m,p, sym(metrical)
in commom name br comes after propyl. in iupac br first then propane.
- Alk-ylidene hal-ide
Anmerkungen:
- Alk-ylene dihal-ide
Anmerkungen:
- pg 284
Anmerkungen:
- Bond nature
Anmerkungen:
- 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
- B.enthalpy, length, Dipole m.
- size increase down the group
- Method of preparation
- From Alcohols
- Cl- ZnCl2
- Br- NaBr+H2So4.H
