oxygen is electron rich and both carbon and hydrogen are electrophilic‚ as shown in the drawing on the right. Indeed‚ the dipolar nature of the O–H bond is such that alcohols are much stronger acids than alkanes (by roughly 1030 times)‚ and nearly that much stronger than ethers (oxygen substituted alkanes that do

Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy‚ which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region‚ which is made up of gamma‚ X‚ and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination‚ and traits. We must be aware of the functional groups

according to the number of the C atoms attached to it. Nomenclature 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.

dispersion forces). The magnitude pof Van der Waals force depends on the relative molecular mass‚ high mass produces a larger force. Boiling points of the alkanes data and alkenes data These very clearly illustrate the effect of increasing Van der Waals attractions as the relative molecular mass increases. The influence of branching in the alkanes can also illustrate the effect of different surface areas on the Van der Waala forces (the more branching the lower the b.p) Dipole-dipole forces --

chloride was synthesized through the use of separation (aqueous and organic layers) and distillation. Tert-butyl chloride is the alkyl halide which is being synthesized throughout the course of the experiment. Alkyl halides are derived from alkanes. Once an alkane has its original hydrogen atom replaced with a halogen‚ it is now considered an alkyl halide (UC 2016). This experiment utilizes chlorine as the halogen that takes the place of the hydrogen atom. Alkyl halides are versatile‚ and with little

industrial applications. In general the methods used include physical processes such as filtration‚sedimentation‚ and distillation‚ biological processes such as slow sand filters or biologically active carbon‚ chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. Nowadays‚ people who sell purified water sells water expensive. In this study‚ we would like to propose if using malunggay seeds would purify water. STATEMENT OF THE PROBLEM The

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because
