any alkyl group‚ a primary halide has one alkyl group‚ a secondary halide has two alkyl groups‚ and a tertiary halide has three. Synthesis of alkyl halides can be performed from a variety of starting materials and specific mechanisms: from alkenes by addition‚ from alkanes by substitution‚ and from alcohols via nucleophilic substitution. The reaction of alcohols with hydrogen halides‚ like HCl‚ HBr‚ and HI‚ would result to their corresponding alkyl halides and water. The formation of alkyl halides
Premium Hydrochloric acid Hydrogen Chlorine
Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

of haloalkanes Haloalkanes are named by adding prefix fluoro‚ chloro‚ bromo or iodo to the name of the corresponding alkanes. Physical properties of haloalkanes Haloalkanes have stronger intermolecules force compared to alkanes and alkenes.

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

ELECTRONEGATIVITY This page explains what electronegativity is‚ and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegativity in an organic chemistry context‚ you will find a link at the bottom of this page. What is electronegativity Definition Electronegativity is a measure of the tendency of an atom to attract a bonding pair
