One gram of a bromoalkane on heating with excess silver nitrate in Carius tube method gave 0.94g of yellow precipitate. What is the percent weight of halogen?

Text Solution

Verified by Experts

eight of substance = 1g , Yellow precipitate is AgBr , Weight of AgBr = 0.94g
Weight percentage of bromine = `("weight of AgBr" xx10xx80xx100)/("weight of substance"xx188)=(0.94xx80xx100)/(1xx188)`
Weight % of bromine = 40line in IR region.
