Calculation the reaction of phenol with bromine


The reaction of phenol with bromine molecule gives 2,4,6-tribromophenol. How many moles of bromine molecule are required in order to get 298g of 2,4,6-tribromophenol from 94g of phenol? The reaction is supposed to proceed theoretically. Here, atomic masses are H =1 , C=12 , O=16, Br= 80

How should i start
is this reaction right?
2C6H5OH + 3Br2 ---> 2C6H3OBr3

This is a simple stoichiometry problem.

First, balance your equation (you're missing a product- where does the rest of the hydrogen go?).

Then find your moles of your known substance (the amount of product you're hoping for), then use your mole-to-mole ratio to find out how many moles of bromine you need.




Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
