Synthesis of Chloroform -------------------------------------------------------------------------------- With Calcium Hypochlorite and Acetone When chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone

test solution was put in the tube. Five drops of 10% NaOH and 2 drops of 0.5% CuSO4 were added to this tube. If a purple color showed‚ it would indicate there was protein in the test tube. In the third separation of this experiment‚ the hood in the lab was used. The curds were placed in a 100 mL beaker and extracted using 30 mL of ethyl acetate. The curds were crushed with a stirring rod. This extraction was then gravity filtered through a funnel fitted with the filter paper. A rubber policeman was

Synthesis Essay In today’s society‚ language is one of the most important and most used things in everyday life. Language is one of the most effective and efficient ways of communicating with one another‚ animals‚ and God. It can be used as a mirror‚ tool‚ or a weapon. The reason I think language can be used as a mirror is because people use language to directly reflect who they are as a person. For example‚ if you have heard someone using improper grammar or slang‚ it may lead you to believe

Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized

Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches

Synthesis Essay In our world‚ we constantly encounter problems. There will be more significant and life-changing obstacles‚ and also many smaller‚ less threatening ones. But what matters most is not the size or relevance of those challenges‚ but instead‚ it is more important as to how one deals with the problem. Adversity of all different types and sizes reveals one’s character. One type of adversity‚ physical adversity‚ happens in various ways. In Mitch Albom’s book‚ Tuesdays with Morrie‚ Albom

replication in a eukaryotic cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts. Also eukaryotes synthesize the same time they are being transcribed‚ and ribosomes will be active

October 9‚ 2013 Partner(s): Acetylsalicylic Acid Synthesis Theory. This experiment was carried out to see how the hydroxyl group on the benzene ring in salicylic acid reacts with acetic anhydride to form an ester‚ and to make aspirin. Synthesis of Acetylsalicylic Acid occurs by protonation of carbonyl (C=O) group‚ and a nucleophilic attack of OH on the acetic anhydride. The ferric chloride test and melting point were used to test the purity of the results. A hypothesized recovery rater of above

Brianna Williams Block: 8th November 22‚ 2013 Synthesis Essay Sojourner Truth in her speech‚ "Ain’t I a Woman?" demonstrates that she’s tired of inequality and fights for women’s rights by having comebacks to the white men that don’t think negro women like herself should have rights. In Malala Yousafika’s interview‚ she views education as a gift and feels girl should also have the right to go to school. Both of these women feel women are as capable as men.
