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
