unimolecular

Examples of unimolecular in the following topics:

• Elimination

  • Like nucleophilic substitution, it can occur via unimolecular or bimolecular mechanisms.
  • A common example of elimination is the dehydration reaction, which occurs in a unimolecular process:
  • In unimolecular elimination (E1), a leaving group first detaches itself from a carbon atom, leaving behind a carbocation.

• Molecularity

  • If a single species makes up the transition state, the reaction would be called unimolecular.

• Other Reactions

• Nucleophilic Substitution

  • This will be explained further in the detailed sections on unimolecular and bimolecular forms of nucleophilic substitution.
  • In unimolecular nucleophilic substitution (SN1), a leaving group is replaced by a nucleophile in a two-step process.

• Rate Laws for Elementary Steps

• First-Order Reactions

  • As such, a first-order reaction is sometimes referred to as a unimolecular reaction.

• Elimination Reactions of Alcohols

• Oxidation States of Nitrogen

  • Amine oxides are not the only functions that undergo a unimolecular syn-elimination on heating.

• Alkene Isomerization

  • Unlike the previously described unimolecular isomerizations, this compound is formed by a bimolecular reaction between an electronically excited stilbene and a ground state stilbene molecule.
