stereochemistry General Concepts The most common of the variety of methods available for preparing alkyl halides is the replacement of the hydroxyl group of an alcohol. This type of reaction is representative of an important class of reactions in organic chemistry called nucleophilic aliphatic substitution reactions. There are numerous ways of doing this transformation‚ and we will discuss these in lecture. In this experiment you will convert an alcohol to an alkyl halide by reaction with a hydrohalic

The compound is the substance that can be two or more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if

the market everyone experiences the same thought: “Organic or regular?” If one does decide to go organic‚ a few things come to mind: Is organic worth the price? How do I know if it really is organic? Why should I buy the organic five-dollar raspberries‚ while the normal raspberries are only two dollars? These are thoughts that strike every one’s minds while shopping at their local super market. The majority of people would turn away from organic products due to the price. Not only is the price a

constructed category of people who share biologically transmitted traits that members of a society consider important. Racism: the belief that one racial category is innately superior or inferior to another. In today’s society‚ the relation between race and racism go hand in hand‚ even though they are completely different. Minorities are victimized every day because of the color of their skin‚ hair texture‚ and facial features. Primarily‚ people tend to see only three racial categories: Black‚ White

impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting

Rationale Abstract: This investigatory project was conducted to test the affectivity of organic and synthetic fertilizers when apply on okra plant. It also aims to test whether‚ which is better to use between the two fertilizers. In order to conduct the study we have used okra seeds‚ polyethylene bag and cemetery soil as organic fertilizer‚ synthetic fertilizer‚ and black soil‚ labeled it as setup A (Organic Fertilizer) setup B (Synthetic Fertilizer). Then we observed the changes in the plant for

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond

The two primary sources of organic compounds are oil and coal. Other sources of organic compounds are plants‚ animals‚ and microorganisms. Hydrocarbons are organic compounds that contain only carbon and hydrogen. There are various classifications of hydrocarbons. Classification
