    ------------------------------------------------- MELTING POINT AND BOILING POINT OF ORGANIC COMPOUNDS ------------------------------------------------- ABSTRACT The melting point (MP) and the boiling point (BP) are probably the most widely used physical constant in the field of science. Determining the boiling point and the melting point of a compound helps you to characterize an unknown solid in a quick‚ easy and cheap way. The temperature at which a compound turns from a solid state to a liquid state is known to be the

    refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical properties. The properties were then compared to those of known compound to make an identification. The properties determined included density‚ boiling point

    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

    Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

    Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

    Preliminary Analysis Samples tested in this lab are sample numbers: 1‚2‚3‚4‚5‚8‚9‚10‚14‚16‚22‚ and 23. Using various test‚ we found characteristics about each individual sample which gave us a better idea on whether the sample is living‚ dead‚ organic‚ or inorganic. This is the same as our proposed study because we are trying to see if samples are dead‚ alive‚ organic‚ or inorganic. Notices our results are based on the whole group of tested samples‚ some results in recorded data as a whole
