When synthesizing n-butyl bromide by allowing n-butyl alcohol to rect with sodium bromide and sulfuric acid what are the formulas for the salts that may precip. when the reaction mixture is cooled?

Answer 1

CH3CH2CH2CH2OH + NaBr --> CH3CH2CH2CH2Br + NaOH.
NaOH would react with H2SO4 to form Na2SO4 which may precipitate in a mixture of organic solvents.

Answer 2

to form crystals
