CHEM 3305 - 001 Organic Chemistry 1 Dr Michael Findlater Spring Semester‚ 2013 Stereochemistry • Stereochemistry refers to the three-dimensional structure of a molecule. • As a consequence of stereochemistry‚ apparently minor differences in 3D structure can result in vastly different properties. • We can observe this by considering starch and cellulose‚ which are both composed of the same repeating unit. Stereochemistry of Starch and Cellulose Figure 5.2 • In cellulose

and Aromaticity Introduction: • All organic compounds can be derived into two broad classes 1. Aliphatic compounds Nonaromatic hydrocarbons such as alkanes‚ alkenes or alkynes 2. Aromatic compounds A series of cyclic unsaturated compounds with unusually high stability • The properties and reactions of aromatic compounds are exemplified / demonstrated by the properties and reactions of benzene (the “parent” aromatic molecule) • Benzene Structure: MF: C6H6 DBE = • Properties and Reactions

Importance of Organic Foods The definition of organic agriculture is farming with the use of synthetic chemicals. After World War II‚ larger and increasingly automated farms‚ known as "factory farms‚" put the synthetic fertilizers‚ pesticides and herbicides developed in the 1920s into widespread use. They found that more crops could be produced mass produced. What they did not realize were the dangers of using these chemicals and the effects they would have on the environment and human health

“Organizational Structure” Introduction: Organizational structure provides the framework of an organization determining how roles and responsibilities are delegated throughout the different levels of the organization. It has been defined by some as the looking glass through which coworkers see their organization and its surrounding environment while others have described structure as the backbone of the organization.

Why Centralized Health Care Failed (AKA; How I learned to Hate the System) An old woman wakes up to the sound of coughing next to her. Her husband has been sick for weeks now‚ and his raspy wet choking seems to be only getting worse. She tries to go back to sleep‚ but she can’t; her thoughts are filled with uncertainty and fear; they have no insurance‚ and they cannot afford to go to the hospital. This is just one casualty of America’s war with itself over Health care. As of this writing‚

Most grocery stores now sell food products labeled “organic” due to the increase of demand. Organic food became popular in the 1990’s and has since remained a trend. Although there are more and more supermarkets stocking organic food products on their shelves‚ non-organic food products seem to outnumber the amount of organic food products. Organic food products are labeled with a green and brown sticker that says USDA ORGANIC. When most Americans see this label they think that what they are buying

Patricia Williams ENG 226 DL3 Is Organic Food Better? There have been many different food trends over the years. We have been told about eating low fat diets‚ zero carb diets‚ and now organic. If you are like many others‚ there is a good chance that you have heard that organic foods are healthier to eat. They contain more vitamins‚ minerals‚ enzymes and taste than engineered produce do. Organic foods are also free from insecticides‚ pesticides‚ growth hormones‚ antibiotics‚ fertilizers and a

Organic agriculture‚ seen as a niche agriculture sector‚ is promoted as an effective and sustainable approach to food security‚ farmer’s profit instigation‚ and resource management. Aside from organic farming‚ the Department of Agriculture welcomed agricultural activities that encouraged active in the preservation of the environment‚ such as agriculture tourism and ecotourism as an additional initiative for agricultural development.
