In this example, tert-butyl bromide ( C H 3 ) 3 C B r (CH 3 ) 3 CBr ( t B u B r tBuBr) reacts with the strong base ethoxide C H 3 C H 2 O - CH 3 CH 2 O - ( E t O - EtO - ), producing the alkene isobutylene ( I B IB), ethanol C H 3 C H 2 O H CH 3 CH 2 OH ( E t O H EtOH), and the bromide ion B r - Br - . This reaction is carried out using dry ethanol as a solvent ( a l c alc).
