SN1 Reactions For SN1 reactions it’s important to have a good leaving group because this reaction occurs in two steps. Because alcohol is such a poor leaving group it needs to be helped by silver nitrate to help promote the ionization of the alkyl halide. This helps form the products of the SN1 reaction. 2-chlorobutane This reaction didn’t occur because the carbocation isn’t stable enough for an SN1 reaction. 2-bromobutane This reaction occurred in 32 seconds. This reaction occurred quickly

The Holocaust effected millions of people Hitler wanted an all Aryan race because he was filled with hatred towards polish citizens. He killed Jew and everyone who didn’t have blonde hair and blue eyes. All Polish citizens had to pay the price of death because of racial issues. Hitler wanted to kill mostly all the Jews. He didn’t only kill Jews though‚ he killed Muslims‚ too. Polish citizens had to work for Hitler and Hitler’s soldiers. They were sent to concentration camps. They were forced labor

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

there are other reasons for these actions but as it has been mentioned before that humans are moral animals in the sense that blood has to be spilt for we know is unjust. The hatred of Hitler towards the Jews also exposes the evil nature of Man. The holocaust is by far the worst expression of Man’s evil nature. Millions of people died in the hands of Hitler. Large populations died through the system he set to wipe out a large population (genocide).It takes a lot to kill just one person but now killing

The reading of the Holocaust victim’s names was a bleak reminder of a trip I took with a friend to Germany in 2006. We visited many beautiful places including breathtaking castles and mountains‚ but the most memorable experience I have from our trip was visiting the Buchenwald Concentration Camp near Erfurt Germany. I was taught in school growing up that the Holocaust was bad. I was aware that genocide was attempted and many people were killed. It sounds terrible to say‚ but I had become numb

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

During this assignment‚ I learned firsthand just how hard it was for Anne and her family along with all the other families during the holocaust. Early on as I began this assignment‚ I grabbed a text book and began to take notes for another class. Right there is when I realized just what a struggle it must have been for Anne. How could she write so much in her diary when she could barely see what she was writing? I know this because the blinds in my room are white and let some light in‚ while her

Flatland Reaction Paper Prior to reading this article‚ I never really thought of math to be this universal thing that could be applied over such a large horizon. I was knowledgable that‚ of course‚ everyone and everything could be eventually linked in some way or fashion to mathematics‚ but I was oblivious to how large of a spectrum it all really sits. Overlooking all of the sexist and biased opinions stated by Edwin A.Abott in this piece‚ he really opened my eyes to a different perspective of
