Answer to Question #40760 in Other Chemistry for akash sharma
0.10 g glycine and 0.4 ml water taken in 5 ml conical vial. Warmed slightly to dissolve the glycine. 0.3 rnl acetic anhydride added and stirred for about 5 min. Mixture cooled in ice bath for 10 min. Precipitate collected by suction filtration and washed with a few ml water. Clystais spread over a piece olfiiter papel or watch glass and air dried for i0 min. Mass and melting point of product recorded. Glycine dissolved after about 20 sec when warmed in gl5 cine water mixture' White, needle-shaped crystals formed when reaction mixture cooled in ice. 0.14 g. of solid obtained after f,rltration and drying of product. mp of crystals recorded as 205-207 n Solid product possibly still slightly wet. Conclusion: crystallized material was in fact acetanilide, based on its melting point. Not highly pure. A second crystallization should produce a fairly pure material, but it would also decrease

Hi Expert, so I wasn't able to try the new version because they closed of the submission portal. Oh well,
but I want to give you my sincerest thank you for helping me throughout this assignment! Honestly, you are an absolute legend! Your line by line explanation was superb and honestly helped me understand most of the concept I learnt during my semester better than my own lecturer! Thank you for consistently helping and being persistent with the versions!
You've honestly been the greatest help and I would have been so lost if it wasn't without your expertise!
So thank you once again!
