A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.

Organic Chemistry Laboratory Report. Experiment 1: Crystallization. Objectives: 1. To study the crystallization process. 2. To identify the best suitable solvent to use for the crystallization process. 3. Gain an experience in purifying an organic compound by the techniques of the crystallization. Introduction. Crystallization is a technique which chemists use to purify solid compounds. It is one of the fundamental procedures each chemist

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic

Amanda Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric

Research Proposal Consumer Attitudes and Purchase Intentions in Relation to Organic Foods in Peninsula Malaysia Abstract The aim of this study is to find out the three (3) significant variables forming the positive attitude towards the buying the organic food in Peninsula Malaysia‚ which eventually lead to the ultimate intention in buying the organically-produced food. The different variables are focused on demographic characteristics on household income‚ product attributes and lastly the

higher than the corresponding alkane with the same number of carbon atoms. Compare ethane and ethanol: Ethanol is a longer molecule‚ and the oxygen brings with it an extra 8 electrons. Both of these will increase the size of the van der Waals dispersion forces and so the boiling point. If you were doing a really fair comparison to show the effect of the hydrogen bonding on boiling point it would be better to compare ethanol with propane rather than ethane. The length would then be much the same
