Problem- Consider the Williamson ether synthesis between 2-naphthol and allyl bromide in the presence of a phase transfer catalyst and strong base in dichloromethane solution.
A reaction was performed in which 0.39 g of 2-naphthol was reacted with a slight excess of allyl bromide to make 0.34 g of allyl 2-naphthyl ether. Calculate the theoretical yield and percent yield for this reaction.
