Answer #1

Suice amount of aniline used is less, Ituefore aniline is the limiting reagent. - - Molar mass of Aniline = 93.13 g/mol massMolav mass of 2,4,6-tribromomiline = 329.817 gmals Theoveliced yield = moles of limiting veagent * molav mass of prochet - =... piphate % yield = Achial yield xloro d Theo reticel yielde = 23.617. g. Xloo 35.5678 = 66-4014% 1 Answer = 66
