The Iodination of Salicylamide Questions: 1. a) The possible sites of iodination of the salicylamide ring is on the ortho/para position to the -OH group. b) The most likely site of iodination is the para position. This spot has the least steric hindrance and is favorable due to the directing effects of the -OH and the withdrawing effects from the carbonyl. 2. The homo surface shows that salicylamide has large electron density at the para and ortho positions. These sites are more likely

The Atomic Model has changed over time‚ as the years‚ decades‚ and centuries go by we get a better understanding of the atom and what it looks like. The Atomic Model has changed drastically based on the understanding we have on it‚ each new model has added more information to what we know about it‚ making it easier for scientists and the world to understand. The Atomic Model is a very important part of Science and Chemistry‚ it helps explain the structure and what is inside the atom‚ the particle

Albert Einstein‚ one of the greatest scientists of the twentieth century‚ received a letter from Phyllis Wright in 1936. In this letter‚ Phyllis asks Einstein whether or not scientists pray. In his response‚ Einstein’s purpose was not only to answer Phyllis’ question‚ but he wanted to express to the public that everyone has a belief in the unknown‚ whether it be religion or scientific knowledge. Einstein uses words which mirror those used in religion and a neutral diction‚ and he structures his letter

Zachary Bishop The effect of distance between dominoes and time taken to fall Introduction By collecting data whilst keeping all variables constant apart from the independent and dependent variables of an experiment‚ it is possible to determine a relationship between them. One relationship that can be observed in a laboratory is the relationship between the distance (denoted by symbol d) of separation of dominoes in a domino chain and the time taken (denoted by symbol t) for all dominoes to fall

To keep the syringe air tight. (1) 3. As the temperature should be kept constant‚ the gas is allowed to return to the room temperature after the air is expanded or compressed. (2) 4. To check whether there is significant air leakage during the action of piston. (May consider other answers‚ e.g

Experiment 2: Kinematics of Human Motion Abstract: Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis of human motion‚ where displacement vs time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 18.75m‚ average velocity
