EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Purpose: The purpose of the lab was to investigate and demonstrate hydrogen bonding and London dispersion bonding in water and rubbing alcohol. Hypothesis: I believe water will have the greater surface tension because rubbing alcohol’s density is lower than water’s. Materials: * Water * Isopropyl alcohol (rubbing alcohol) * Pennies * Paper clips * Flasks * Cups or jars * Wax paper * Eyedropper Procedures: Part 1: Surface tension and vortex: * Fill

the previous generation used to be‚ Fishman’s evidences are more up-to-date. According to a recent Sun editorial‚ “activism has transformed from sensationalized 1960s tear-gas rallies to online petitions and Internet discussion boards” (Fishman 73). Not only Fishman‚ but also the reality tells that the time has changed. News can be spread worldwide in seconds through the Internet‚ and it can easily gather “Generation Q”‚ written by Thomas L. Friedman‚ and “The Generation of Generation Q”‚ written

Our Generation If you spend much time with your kids‚ you quickly realize that the next generation of teens is much unprepared to deal with the real world. They are overweight‚ lazy‚ undisciplined‚ disrespectful‚ and disobedient to their parents‚ selfish‚ self-centered‚ and completely addicted to entertainment. And that is just for starters. Their parents feed them insane amounts of sugar and high fructose corn syrup and then when they become overactive we pump them full of prescription drugs

Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

Reaction of catalase with hydrogen peroxide AIM: I aim to find the rate of reaction between catalase and hydrogen peroxide. Enzymes such as Catalase are protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. Each enzyme just performs one particular reaction so they are all very specific. Catalase enzymes found in living cells e.g. in yeast‚ potato or liver‚ speed up (in our case) the breaking down of hydrogen peroxide. The lock and key analogy…

Abstract The decomposition of hydrogen peroxide (H2O2) in a whole and diced wedges by with The enzyme catalase was observed. The catalase was able to break down the hydrogen peroxide In the diced banana wedge better than the whole banana because after the banana was diced that Increases the surface area allowing the breakdown to flow. The effects of temperature on enzyme In a liver sample were observed under iced‚ boiling‚ 37 degrees‚ and room temperature Conditions. The enzymes became completely

RED is taking its knowledge of high-quality cinema cameras to the smartphone industry with a new product. The Hydrogen One is RED’s bet to revolutionize the use of smartphones. Back in 2006‚ when RED was founded and showed its intent on delivering high-performance digital cinema cameras with quality of 35mm film and the convenience of pure digital‚ many people were skeptical and some even considered it a “scam”. After a 10-years background of providing unique high-quality cinema cameras with high-usage

Different kinds of liquids stain your teeth differently. For example tea stains your teeth more than milk does. I’m doing this experiment because I think it is very interesting that there are so many different kinds of liquid that can stain your teeth. What things stain your teeth? To start with you should never start smoking or use tobacco. The nicotine and tar in the cigarettes stain your teeth very drastically. You can’t even imagine how fast smoking stains your teeth. Other things that stain

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during
