COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid. The

AND PURIFICATION OF ORGANIC COMPOUNDS AIMS: To isolate organic‚ inorganic and component from a given sample. To become acquainted with various separation methods. To examine the solubility behavior of the various compounds in a mixture using different solvents. INTRODUCTION A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at

Volatile Organic Compounds (VOCs) have become the greatest challenges to the preservation of the environment today. This group of chemicals is used in almost every sphere of life from industries‚ government institutions and domestically by both an ignorant and knowledgeable public. This paper aims to put to light examples of such compounds‚ look at the effect on the general populace and the environment and outline possible remedies to negative impacts. At the same time‚ it is important to look at

VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile organic chemical”

producing another action potential (Stillman‚ 2005). In this lab‚ compound action potentials (CAPs) will be measured from an isolated sciatic nerve from a cane toad‚ Bufo marinus. Compound action potentials are the total sum of action potentials from the multitude of neurons that compose a nerve (Stillman‚ 2005).

Physical properties of organic compound Low boiling point group: alkane‚ alkene‚ alkyne and ether Boiling point is the exact temperature that the state of compound change from liquid to gas‚ which need to break the intermolecular forces. The stronger the intermolecular forces‚ the higher the boiling point. Since straight chain alkane‚ alkene and alkyne only experience dispersion forces‚ the compound with more carbons have higher boiling point as more carbons contribute more forces. Branched

ups Identifying food groups in unknown solutions Aim The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added‚ some will change colour while others will separate. Introduction Food is a vital source of energy that is

Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are
