anhydrous methanol; thiourea; carbon tetra-chloride Introduction Crystalline inclusion complexes represent an intriguing class of supramolecular assembly that continues to receive considerable attention. The rational design of composite solid state materials has many potential applications in areas such as chemical preparation‚ crystals engineering and non linear optics. One tactic commonly employed in the synthesis of potential inclusion hosts is the incorporation of functional groups

Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

Stoichiometry of a Precipitation Reaction Purpose: The purpose of this lab is to calculate the theoretical‚ actual‚ and percent yield of the product from a precipitation reaction. Also‚ to learn concepts of solubility and the formation of a precipitate. Procedure: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ Add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small

and Growth of Semiconductors In studying solid state electronic devices we are interested primarily in the electrical behavior of solids. However‚ we shall see in later chapters that the transport of charge through a metal or a semiconductor depends not only on the properties of the electron but also on the arrangement of atoms in the solid. In the first chapter we shall discuss some of the physical properties of semiconductors compared with other solids‚ the atomic arrangements of var- ious materials

alcohol #1 = 108oC -109oCObservationWhen the NaOH was added to the aldehyde #1‚ the solution turned yellowish green. It took 10 minutes for the white solid NaBH4 to completely dissolve in the aldehyde solution. When the HCl was added‚ the solution fizzed and bubbles came off. White precipitate formed. After the vacuum filtration‚ shiny white crystalline solid was found. DiscussionFrom the melting point range of the alcohol 108oC -109oC‚ it could be determined that the aldehyde isomer used should be vanillin
