BACHELOR OF SCIENCE (HONS) BIOTECHNOLOGY YEAR 1 SEMESTER 1‚ 2 & 3 UDBB 1164 FUNDAMENTAL ORGANIC CHEMISTRY 0 EXPERIMENT 1 PROPERTIES OF HYDROCARBONS Introduction Hydrocarbons are compounds which contain only carbon and hydrogen‚ can be classified into several types‚ depending on their structure. Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction of a gram of product. The second part of the lab makes use of NMR Spectrometry. NMR takes advantage of the magnetic properties of the 1H & 13C nuclei. We are only concerned with 13C because 12C does not have

Renee Alyanna de Leon IV- St. Arnold Janssen The island province of Bohol reinvigorates its tourism promotion with a campaign that is said to “go deep into the roots emotionally.” Its local government recently launched a tourism campaign with the slogan “Bohol: Heart the Islands‚ Truly Philippines.” The slogan points out that the island is at the center of the Philippines‚ being in the Central Visayas Region and Visayas being at the center of the country. It is also usually projected as a truly

Energy Flow Systems Richard White’s Organic Machine‚ and William Cronon’s Changes in the Land‚ both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White’s thesis is to examine the river as an organic machine‚ as an energy system that‚ although modified by human intervention‚ maintains it’s natural‚ its "unmade" qualities. White emphasizes on energy because it is a useful concept that can be easily

Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance
