with 90% yield whereas Bromobenzene takes 70 minutes for completion of the reaction. There was a vigorous reaction in case of Nitrobenzene. Evolution of HCl was observed during the reaction. The reaction mixture becomes viscous and sticky for which separation became difficult. The reaction was faster with 1‚3-DiChlorobenzene whereas 1‚4-DiChlorobenzene was inactive towards Benzylation in presence of ZnO/ZrO2 at 80oC under solvent-free condition. CONCLUSION: Diphenylmethanes are industrially important

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt solution and it is observed that there are 6 (3.9%) plasmolyzed cells. In the 5% salt solution‚ there are
