  1. HO-CH2CH2CH2CH3 (butanol) + H2SO4 (sulfuric acid) + NaBr (sodium bromide) --> Br-CH2CH2CH2CH3 (1-bromobutane) + H2O + NaHSO4

    The reaction is performed by adding 1-butanol and sodium bromide to a flask containing water. Then H2SO4 is slowly added dropwise to the reaction mixture. The reaction is considered to be SN2 because Br(-) anion displaces the hydronium (+OH2) ion as it is produced by the dropwise addition of acid...

    Hope this helps!!!
