www.vanderbilt.eduElimination Reactions: Nucleophiles are Lewis bases. In the reaction with alkyl halides, they can also promote elimination reactions rather than substitution. RCC: _ R X 1° alkyl halide SN2 RCCCH2R RCC: RX HR _ Helimination H RH R 2° alkyl halide Elimination is a competitive reaction with nucleophilic substitution.

www.austincc.eduRelative Rates of Nucleophilic Substitution 6.20 (a) 1-Bromopropane would react more rapidly because, being a primary halide, it is less hindered. (b) 1-Iodobutane, because iodide ion is a better leaving group than chloride ion. (c) 1-Chlorobutane, because the carbon bearing the leaving group is less hindered than in 1-chloro-2-methylpropane.

Alkyl Halides - Rutgers University
crab.rutgers.eduNucleophilic Substitution The nucleophile Nuc:¯ displaces the leaving group (producing X¯) from the carbon atom by using its lone pair to form a new bond to the carbon atom. Elimination A new bond is formed by the elimination of halide ion and another atom (usually H+).

Reactions of Amines - Minnesota State University Moorhead
web.mnstate.edu• Qualitatively, can think of this as a nucleophilic substitution: a nucleophile replaces N2, a premier leaving group. The actual mechanism is probably radical, however. • Application in synthesis: The amine (an o/p director) is often derived from a nitro (a meta director). ...
