Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

Phytochemicals Kritzel Resendez General Chemistry 1412 6th period Mr. R. C. Gonzales May 16‚ 2011 Abstract Phytochemicals are substances found in foods of plant origin‚ biologically active‚ which are essential nutrients for life at least in the short term‚ but have positive effects on health. Found naturally in plants (fruits‚ vegetables‚ legumes‚ whole grains‚ nuts‚ seeds‚ mushrooms‚ herbs and spices). Phytochemicals are beginning to take into account in recent years‚ as they are discovering its health

Introduction: This experiment focuses on carrying out a Perkin Reaction to synthesize (E) and (Z) isomers of α-phenylcinnamic acid. This was accomplished by refluxing benzaldehyde‚ phenylacetic acid‚ acetic anhydride and triethylamine as a base. The chemical equation of a Perkin Reaction can be seen below. The reaction mechanism for the synthesis of α-phenylcinnamic acid is shown below: Results: Theoretical Yield Therefore‚ phenylacetic acid is the limiting reagent. Table

BACKGROUND :- These resins are Thermoplastic Polymers manufactured by copolymerization of cyclic terpene hydrocarbon (like Pinene‚ Carene etc.) and phenol. There are various grades of this resin with softening points ranging from 70 - 110C. These resins are compatible with Natural and Synthetic Rubbers‚ Rosin‚ Alkyd resins‚ and most of the plasticizers and waxes. Applications are in the manufacture of tubes‚ tyres‚ gaskets‚ cables‚ pressure sensitive adhesives‚ hot melt adhesives‚ surgical

Microwaves (3:04) 7. Where are Microwaves found on the electromagnetic spectrum? Microwaves have wavelengths ranging from 30 centimeters down to 1 millimeter. Microwaves fall between radio waves and infrared waves. 8. Describe one thing that C‐Band Microwaves are used for? Medium length C-Band Microwaves are used for revealing the Earth’s surface. 9. What did two scientists discovered by accident using L‐Band Microwaves? The two scientists

to intensify human sight under very low light conditions. Although more human activities are done during the day than night‚ the capability to see in the dark is still significant in many occasions. Night vision devices focuses infrared light to objects in the dark; infrared is beyond spectrum visible to the human eyes. A device for night vision was perfected during wartime giving soldiers in the battle field a technical benefit over their enemies. Vision equipment has evolved from bulky optical

of the chemical formula C10H20O is formed upon catalytic hydrogenation of anise oil‚ it can be determined that the original structure contains four pi bonds‚ as eight hydrogen atoms were added. Through heating with hydriodic acid‚ anisene forms the phenol C9H9OH. This indicates that the major constituent of anise oil is an aryl methyl ether‚ with the chemical formula C9H9OCH3. With the formula rewritten‚ it can be seen that anisene has a disubstituted benzene ring with a methoxyl group (-CH3O). This
