Question

1. Calculate the percent yield of 1- bromobutane obtained when 15.4 g of butan-1-ol was used, and 22.5 g of 1-bromobutane was obtained after purification (NB. The limiting reagent in the production of 1-bromobutane is 1-butanol).

Answer 1

how many moles in 15.4g?
how many moles expected? how many actually produced?
% yield = produced/expected

Answer 2
