Methanol (CH3OH) is converted to Bromomethane (CH3Br) as follows:
CH3OH +HBr= CH3Br+H2O
If 8.01 g of Bromomethane are produced when 4.051 g of methanol is reacted with excess HBr, what is the percentage yield?
I hope this helps you.
Do comment if you have any doubt.
Feedback appreciated..
All the best! :)
