ELIMINATION REACTION - E2- ELIMINATION REACTION - REACTION MECHANISM (ORGANIC CHEMISTRY)
Elimination reaction involves the loss
of two groups are atoms from a Molecule. The reactions are classified under 2
general headings β- elimination (1, 2 elimination), the most
common elimination reaction, in which groups on adjacent atoms are
eliminated with the formation of an...
ELIMINATION REACTION- E1 MECHANISM; E1cB MECHANISM (ORGANIC CHEMISTRY)
E1-
Mechanism:
This
elimination takes place (without the participation of a base) in 2 steps, unimolecular ionization, being rate-determining step.
The main feature of this mechanism
is that under the influence of solvation forces the electron attracting group
(leaving...
PYROLYTIC SYN OR THERMAL ELIMINATION; REGIOSELECTIVITY OF E1 & E2 REACTION (ORGANIC CHEMISTRY)
Pyrolytic
syn elimination reaction (Ei - elimination internal):
This
thermal elimination occurs in a family of a compound like an acetate Esters,
methyl xanthate ester, tertiary amine oxide, sulphoxides and selenoxides which
contain at least one β hydrogen atom with the formation of olefins. ...
HYDROGEN BONDING
The
hydrogen atom which is bonded to an electronegative atom can form a hydrogen
bond to a second electronegative atom. It is thus a force of attraction
between opposite partial charges δ+ charge on H in the OH group
and δ- charge on the O of another group. Hydrogen bond requires
a...
