Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

Lab #5: Grignard Reaction – Synthesis of Triphenylmethanol John Kang Chem 152L Performed: 7/20/04 Date submitted: ________________ Lab Partners: Sang Lee‚ Vicky Lai TA: John Stanko Abstract: This experiment explored the synthesis of triphenylmethanol through the use of Grignard reagents. The percent yield of the product was 10% on a relatively humid day. The melting point was calculate to be 127.2oC with a literature value of 162oC. An IR spectrum of the product was taken and used

the development of innovative ways‚ theories and principles‚ as well as the termination of the doctrine of ‘terra nullius’‚ creating justice for ATSI peoples past‚ present‚ and future. Native title is a legal right on ATSI communities to use land and live on the land which they have an ongoing connection with. Native title was a problem as it was extremely difficult to determine whether Australia was ‘land belonging to no one’. The Indigenous had to prove they had traditional connections with the land

diseases‚ especially cancer. ANTIOXIDANTS are molecules that can donate an electron to another molecule that has an unpaired electron‚ AKA a free radical.. By donating an electron‚ antioxidants help stop the chemical reaction called oxidation. Think of rust- that’s an oxidation reaction. So basically‚ what antioxidants are important for is to help keep your body from rusting (aging). Are We Receiving the Nutrients We Need? Are all Supplements created equal?

While they are still given a small portion of land to live on‚ the plight of the Native American people has been going on since

“Native American Religions” Native American Religions happen to be one of the oldest and most enduring forms of religion. They comprise a large number of distinct tribes‚ states‚ and ethnic groups. Native Americans arrived on the North American Continent fifth-teen thousand to twenty thousand years ago. Native Americans have literally sources that exist from only the last four hundred years even though Native American life covers perhaps twenty thousand years. Over three hundred tribes have
