Question

ithink the answer would be because it is less dense than water so the bottom layer but here goes the question..
if a sample of recently prepared 1-bromobutane is washed successively with water, cold concentrated sulfuric acid, and then very dilute 5% aqueous sodium bicarbonate solution, tell which layer is the 1-bromobutane in each of the three washings.

Answer 1

Just look up the densties of each substance and use them to help you decide.
