Lab 3: Solubility of Organic Compounds Objectives: Understanding the relative solubility of organic compounds in various solvents. Exploration of the effect of polar groups on a nonpolar hydrocarbon skeleton. Introduction: The solubility of a solute (a dissolved substance) in a solvent (the dissolving medium) is the most important chemical principle underlying three major techniques you will study in the organic chemistry laboratory: crystallization‚ extraction‚ and chromatography.

KHS3. To our knowledge‚ most of the studies on Halomonas sp. focused on degradation of monoaromatic rather than polycyclic and heterocyclic compounds. We have demonstrated that H. sp. KHS3 has the ability to growth using phenanthrene‚ fluorene and naphthalene as the only carbon source. Similar ability has been demonstrated by

Solubility is the ability of a substance‚ or solute‚ to dissolve and homogenously disperse throughout another substance‚ or solvent. In order for drugs to be therapeutically effective and bioavailable‚ it must first be highly soluble. Poor solubility and low dissolution rates of drugs in the aqueous gastrointestinal tract lead to decreased bioavailability. Solubilization of poorly soluble drugs is a challenge in the formulation of newly developed drugs. Because many medications are administered orally

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

What is the Difference between Flammable and Combustible Liquids? Put simply‚ flammable and combustible liquids are liquids that can burn. The real difference lies within their flash point range‚ or lowest temperature at which vapours of the material will ignite when supplied with an ignition source. Flammable and combustible liquids are utilised in most workplaces‚ from manufacturing to retail and service entities. To ensure the safety of property‚ people‚ and the environment‚ both flammable
