Abstract Oxidation was found for primary alcohol. When 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments

The Role of DNA in Protein Synthesis DNA is found in the cells nucleus. It is part of the chromosome of the cell. DNA is the molecule that controls the making of protein. Protein is used for the growth of cells and organisms and also for the repair of cells. Protein is also used as an enzyme to speed up reactions in the body. Because of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die

hydroxylic group attacks the positively charged nitrogen from nitric acid attaching it to the molecule. The nitrogen’s electrons are then kicked off on to the oxygen bearing a positive charge‚ creating water. This process formed an organic nitrate. Next‚ water is used to abstract hydrogen from the positively charged oxygen‚ forming hydronium. A carbonyl is formed as well as nitrogen dioxide gas. Simultaneously the oxygen separates itself from nitrogen dioxide by pushing its electrons onto the positively
