Organic chemistry

This semester, I’m in a course entitled Principles of Chemistry I. Currently, I need to learn and store trends of the periodic table. One particularly hard area is electron affinity and ionization energy trends. Electron affinity is how willing an element is to gain an electron, and ionization energy is how willing the element is to lose an electron. Remembering which direction each of those two trends go on the periodic table has been difficult for me. I’m trying to store this information in my long-term memory because it’s information I’ll need in the future. Next semester I am taking Principles of Chemistry II, and the year after I will be in Organic Chemistry. Chemistry is a topic that continually builds on its basic concepts, so this is…

In the very first experimental lab for organic chemistry, students are introduced to the world of the microscale which is very important for the organic chemistry experience. This would become a stepping stone for acquiring all the technique and experience in handling organic compounds safely and also effectively. This means to use the tools provided in order to get a better and much deeper understanding of the chemistry when applying it real time to reactions. In this case, the experiment…

The learning assistants for Professor Bahde’s Organic Chemistry I class, Allyson Dang and I, wanted to give the students a problem to work on involving a reaction mechanism. The students in that class have been struggling in many areas of the subject, but the main issue they have is drawing out reaction mechanisms. Knowing how to draw out reaction mechanisms is one of the most, if not the most important part of organic chemistry. When theoretically reacting molecules, one must know not only…

Extraction was the main method of removing compounds from the sample. The component X was removed from the sample by first adding the organic solvent dichloromethane to the test tube. After aggravation, the component X dissolved into the solvent. Since components Y and Z were insoluble in the organic solvent they remained as solids. The test tube was then placed into a centrifuge and ran for thirty seconds. By doing so, the unsettled solid were forced to accumulate at the bottom of the test…

Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

Organic chemistry is a challenge. So many people have told me how demanding and scary it is, and even though I was terrified coming into this year, I am ready to take on the challenge. It is a challenge that will hopefully end up with a rewarding learning experience as well as prepare me for life after college. Throughout this course, I think that it is vital to know how you learn best, what the professor is expecting of you, as well as how the class is structured and the policies within it.…

Before beginning he experiment the physical appearance of all the chemicals being used needs to be written down. To begin the experiment 3 test tubes must be acquired; a boiling tube, large test tube and a small test tube. The large test tube must be completely dried with a paper towel and labeled R for Reactants. After that is done a piece of weighing paper should be placed on a balance and tared. After make sure the balance is correctly tared, a spatula must be used to collect 2 grams of…

Felsen released an article pertaining this subject. The article, entitled “Can a Lucky Charm Get You Through Organic Chemistry”, gave the general public a somewhat easy-to-read article, which provided an experimental result about how many people believe in magic and what they believe about it. By analyzing the article, it can be seen that the experiment covered multiple highly debatable topics,…

Research Instrument Multiple Choice Identify the choice that best completes the statement or answers the question. ____ 1. Which of these is true of an ice cube? A It is made of vibrating, closely packed tiny particles. B It is made of clumps of particles that glide past each other. C It is made of particles that spread out evenly to fill the container they are in. D It is made of tiny particles that are far apart from each other. ____ 2. Which idea below describes the atomic theory? A Atoms…

Observations were made for a neighboring science teacher. Ms. C (whose name will remain confidential) teaches all marine ecology courses. A class typically filled with juniors and seniors. At the school, this is an elective course taken as a student’s final science requirement for graduation. Most of the students who enroll in the class do not wish to take the harder elective options such as an AP class, physics, or chemistry. I observed the teacher during her first block class while she was…
