Question

how do I find the theoretical yield of p-bromoacetanilide?

Reagent Data! List of all reagents, catalysts and solvents. For reagents and catalysts, the molecular weight, amount used in m or g. number of moles and limiting reagent should be tabelated.

Dear, Student, Suppose, At Btc Immole ammole 30.5. then prod mimole ' which coill be lover Irminole that is brown limfting Reagent, & that monole tot of pole should form (theoretically). Hence product will be 0.5 rumble Co. theoretically According to your question. Ethand - 0.180 mnole Acete and = 0.0 032 windle Acetanilide = 7.4 mmole I Sodium Bromide = 0.0174 morale Sodium hypochloride = 0.3 mmole 1.0174 morale this is limiting fegant Нео Product coill be form 0.0174 mmole (theoretically mmole of brodent X Most of Product Theoretical Tied = Produt) = 0.0174 x 214.06. 3.72 gm Experimental Yield = 0.999 am Exp.
