1.	1,1,2,2- tetrachloropropane was heated with zinc dust and the product was bubbled through ammonical AgNO_3. What is the weight of precipitate obtained?
Answer» 30.0g 29.4g 28.0g 25.7g Solution :The dehalogenation of vicinal tetrahaloalkane gives alkynes. It is done by heating the compound with ZN dust. `:'` 182 g of tetrachloro ALKANE gives 147 gives 147 g of PPT. `:.` 36.4g of tetrachloro alkane gives `(147xx 36.4)/182` = 29.4 g of precipitate
