概览

The bromine-bearing carbon is at the end of the chain. Substitution can replace bromine with a nucleophile, while elimination removes HBr to form propene. Compare it with 2-bromopropane to isolate the effect of substitution at the reacting carbon; solvent, nucleophile and temperature also matter.
