Question

calculate the theoretical yield for the williamson ether synthesis from 0.251g of p acetamidophenol and 0.12mL of bromoethane, which has a density of 1.47g/mL

Answer 1

from image, we can say

139 g of p-acetamidophenol reacts with 109g of ethylbromide for full conversation.

Therefore,

0.251g p-acetamidophenol reacts with of ethylbromide.

But in the system there is only ethylbromide

So, ethylbromide is the limiting reagent

Now, 109g ethylbromide gives 167g of product

Therefore, 0.1764g ethylbromide gives

Therefore the theoretical yield is 0.27g
