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

YOUNG’S DOUBLE SLIT EXPERIMENT Interference Patterns This report will be performed by a group of 3 students viz. Harleen Kaur‚ Rutvi Patel and Sandhya‚ determining the wavelength of light from a laser using a double – slit slide. The laser was shone through the double – slit such that it projected interference pattern onto the paper screen. The experiment will be repeated three times varying the distance between the slit and the screen to understand the effective relationships. The expected wavelength

complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

Its a well-known fact that there has always been and still is a double standard when it comes to men and women’s sexual expression. Men are judged less severely then woman are for the same behavior. Men are encouraged and praised for having multiple sexual partners while women are shamed‚ and name called. A double standard has been found to exist when researchers have examined male and female condom use‚ study participants typically rate the woman’s behavior more negatively and as more inappropriate

to land a Front Side Double Cork 1260 in the half-pipe competition (Bane). In simpler terms‚ the professional snowboarder completed two corked‚ or slightly tilted‚ flips while also making three and a half rotations. Considering the trick’s great difficulty‚ White earned a perfect score of 100 for being the first to conquer the maneuver. In order for someone to land this trick‚ they must first understand how it works. The key to mastering elite tricks like the Double McTwist 1260‚ the Front

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration
