Introduction In an E1 reaction‚ where E stands for elimination and 1 stands for unimolecular. The breaking of the C-LV bond is completed before any reaction occurs between the base to lose a hydrogen and form the carbon-carbon double bond [1]. When the more substituted alkene is the dominant product‚ the reaction follows Zaitsev’s rule. Zaitsev’s rule states that the major product of a β-elimination reaction is the most stable alkene [1].Acid-Catalyzed Dehydration is the elimination of a

INTRODUCTION: Site directed mutagenesis is molecular biology technique that is used to make specific‚ intentional and precise changes to the DNA sequence of a gene or any gene products. It is also used to determine the structure and biological activity of DNA‚ RNA and protein molecules. It is also called as site-specific mutagenesis or oligonucleotide-directed mutagenesis. This method has also found use in understanding important genetic process like DNA conformational analysis and also functioning

This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

Carbonates react with strong acids to give off carbon dioxide and water. Marble is calcium carbonate and thus behaves in the same way: CaCO3 (s) + 2HCL (aq)  CaCL2 (aq) + H2O (l) +CO2 (g) In this experiment‚ I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction. I predict the higher the temperature‚ the faster the reaction rate. This is due to the kinetic theory. The more heat

Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based
