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.
