a sample of a crystalline compound, when heated in an open test tube, produce several droplets of water on the cool upper region of the tube. the residue in water dissolved in water forming a yellow-brown solution, while the original compound formed a colorless solution in water. why should you conclude that the compound is not true hydrate?

2. A colorless crystalline compound when dissolved in water formed a colorless solution . This compound was heated in a clean, dry test tube. This heating produced several drop- lets of water on the upper region of the test tube. The residue was dissolved in water and formed a yellow-brown solution. a. Determine if this colorless crystalline compound is a true hydrate or not. b. Give reasons.

SOLVED PROBLEM 7-3 When the following compound is heated in methanol, several different products are formed. Propose mechanisms to account for the four products shown. CH-Br CH heat CH,OH -OCH; + -OCH PARTIAL SOLUTION With no strong base and a good ionizing solvent, we would expect a first-order reaction. But this is a primary alkyl halide, so ionization is difficult unless it rearranges. It might rearrange as it forms, but we'll imagine the cation forming then rearranging. H. Br: CH...

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...

please answer all parts I am trying to check my
answers.
Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
