Reaction rate

The goal of this lab was to conduct the reaction of 2-methyl-2-butanol with HCl to form 2-chloro-2-methylbutane, and to understand Sn1 and Sn2 reactions, in terms of how they are different and why one is more likely to happen over the other. The OH group in 2-methl-2-butanol is attached to a tertiary Carbon, meaning the reaction should occur via Sn1, a two-step reaction, and Cl should replace the OH group, to form a tertiary halide. HCl was added to 2-methyl-2-butanol and then several…

on several political issues some of which had potential negative impacts on his political career. In his support for Franklin D. Roosevelt's proposal for the second bill of rights he took a bold step and identified a "democratic socialism" in his reaction to the ever widening gap between the rich and the poor sections of the American society. In his explanation of the democratic socialism, Sanders argues that democratic socialism means creating an inclusive economy system that caters for the…

explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate…

area on the reaction rate. Introduction: In this experiment the experimenters will seek to determine what factors determine the rate of a reaction with a catalyst. A catalyst is a molecule that starts a chemical reaction, but it is not part of the reaction it is causing. The experimenters will use pieces cut up potato as an organic catalyst. The potato contain enzymes that will perform the reactions. Enzymes, “are proteins, produced by living cells; they catalyze chemical reactions by lowering…

Nucleophilic substitution Nucleophilic substitution reaction is that in which attacking nucleophile replaces a leaving group. Attacking nucleophile: specie with an electron free pair or negative charge and ability to replace already present nucleophile i.e OH- Leaving group: A specie with electron deficiency or positive charge, negative charge i.e Cl- What is SN1 Reaction:- SN1 indicates the unimolecular nucleophilic substitution reactions. Their rate determining step of the mechanism depends…

was done with three different reactions, each under different conditions. The reactions were evaluated using the TLC plate to see how far each reaction progressed. During the experiment reaction test tube 2 had the darkest yellow color out of the three reactions. On the TLC plate the starting material had one dot, with an Rf value of 0.22. Reaction 1 had two dots, with Rf values of 0.29 and 0.55. Reaction 2 had two dots with Rf values of 0.24 and 0.53. Reaction 3 had two dots with Rf…

Discussion Enzymes are biological catalysts that help speed chemical reactions. In part A (table 2), it was seen that a normal reaction of catalase and hydrogen peroxide resulted in the release of bubbles (oxygen gas) and the release of energy in the form of heat which shows that the reaction was a exothermic reaction. The reaction was given a reaction rate of four and acted as the control with which we could compare the other results to. When testing whether or not catalase is reusable in part…

"unimolecular nucleophilic substitution reaction", one of the most common reactions in organic chemistry. As a fundamental reaction type, the mechanism of SN1 reaction has long been clear to the researchers, and the rate of the reaction concluded from the mechanism is quite simple. According to the mechanism, the rate of an "ideal" SN1 reaction is only proportional to the concentration of the substrate, which can be expressed as the following formula: rate=k[RX] ([RX] is the concentration of the…

What is SN2? This is a Nucleophilic Substitution reaction where there are 2 components in the rate determining step. It occurs simultaneously as bonds are made and broken at the same time. During the backside attack, a nucleophile attacks the electrophile from the back and causes an inverse in configuration. This attack causes a leaving group to leave. A transition state is formed while this reaction occurs, which is when the leaving group and nucleophile are attached at the same time. What…

Blue Bottle Experiment Problem: The purpose of this lab was to determine the oxidation rate of the Methylene blue solution when tested with varying amounts of solution. Background: The Blue Bottle Experiment is a classic demonstration of a Reversible oxidation-reduction reaction with an alkaline solution of glucose that acts as a reducing agent. It is known that, “Methylene blue speeds up the reaction, acting as an oxygen transfer agent.”…
