E2 is a single step elimination, with a single transition state. It is typically undergone by primary substituted alkyl halides, but is possible with some secondary alkyl halides and other compounds. The reaction rate is second order , because it's influenced by both the alkyl halide and the base (bimolecular).
Tosyl group (blue) with a generic "R" group attached Tosylate group with a generic "R" group attached. Note the extra oxygen, compared to plain tosyl. In organic chemistry, a toluenesulfonyl group (tosyl group, abbreviated Ts or Tos [nb 1]) is a univalent functional group with the chemical formula −SO 2 −C 6 H 4 −CH 3.
Hammond's postulate (or alternatively the Hammond–Leffler postulate), is a hypothesis in physical organic chemistry which describes the geometric structure of the transition state in an organic chemical reaction. [1] First proposed by George Hammond in 1955, the postulate states that: [2]
In organic chemistry, Zaytsev's rule (or Zaitsev's rule, Saytzeff's rule, Saytzev's rule) is an empirical rule for predicting the favored alkene product(s) in elimination reactions. While at the University of Kazan , Russian chemist Alexander Zaytsev studied a variety of different elimination reactions and observed a general trend in the ...
Hofmann elimination is an elimination reaction of an amine to form alkenes.The least stable alkene (the one with the fewest substituents on the carbons of the double bond), called the Hofmann product, is formed.
An important factor in the antiperiplanar conformer is the interaction between molecular orbitals. Anti-periplanar geometry will put a bonding orbital and an anti-bonding orbital approximately parallel to each other, or syn-periplanar.
In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon-halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine ), dechlorination (removal of chlorine ), debromination (removal of bromine ), and ...
Founded on a few general principles that govern how orbitals interact, the stereoelectronic effect, along with the steric effect, inductive effect, solvent effect, mesomeric effect, and aromaticity, is an important type of explanation for observed patterns of selectivity, reactivity, and stability in organic chemistry. In spite of the ...
