Supramolecular chemistry

Conclusion: After observing the evidence that we received from this experiment it is clear that the results thoroughly support my hypothesis. Within my hypothesis I had stated that the melting order from first to last was, as follows, paraffin, glucose, sucrose, and finally, salt. The results that we gathered supported this exact hypothesis. The first substance to melt was indeed paraffin and the second was glucose, and then sucrose and finally salt. The results are supported by the basic knowledge of intermolecular forces regarding hydrogen bonds, London Dispersion forces, as well as Dipole-Dipole, and simple ionic bonds in the case of sodium chloride. The molecule with the least amount of these forces is the one with the weakest bonds, which leads to a low melting point. Paraffin melted first and this is a reasonable result that can be trusted because paraffin has only one intermolecular force, London Dispersion forces. Dispersion forces are known to be the weakest of all intermolecular forces, which is why paraffin melted first. Second to melt was glucose and this result is also reliable due to the fact that glucose contains only a low amount of each intermolecular force. Although all forces may be present the amount is low compared to sucrose and that is why it melted second. Glucose has London dispersion forces and is polar leading to dipole-dipole and contains hydrogen bonds. This makes it have substantially stronger bonds than paraffin however, glucose has a lower…

Abstract In this study, a CO2-respensive GM-AD-HA hydrogel derived from electrostatics crosslinks and supramolecular bond will be produced and studied about its mechanical properties and physiological performance. It is expected to have application in restoring cartilage and controllable delivery of Epirubicin Background of research Hydrogels have crosslinked microstructure and can swell up in water without resolving. Their soft and rubbery nature minimizes inflammatory reactions of the…

the silver to an ion named edmen by the researchers who used and examined this silver (I) saccharinate complex. In the article this complex if referred to as complex 1. The research conducted in the article I selected is important because of the attention which has been gathered by the field of supramolecular chemistry. The reasoning behind this attention is because of the diverse structures of the complexes which can be created. According to the authors of the article these complexes have,…

Introduction Stereochemistry alludes to the science that reviews the properties of stereoisomers. It can likewise be characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary…

How the changing mass of solute effects the heat given out when dissolved in water Aim To investigate how the changing mass of a solute will affect the energy given out. Introduction Dissolving is when a solute is mixed into a solvent to form a solution. Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings…

The purpose of this experiment is to observe the difference between ionic and molecular compounds using conductivity as a means of analysis. This lab will allow us to organize compounds based on the magnitude of their conductivity. This will allow us to determine whether or not a compound is molecular or ionic based on its conductivity. This lab also will determine the effect of concentration on conductivity of certain electrolytes, as well as the number of ions. We also will examine the effect…

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,…

THE EFFECTS OF OSMOSIS INTRODUCTION Osmosis is the process where molecules of a solvent are prone to pass through a semi-permeable membrane, going from a less concentrated solution to a higher concentrated solution. Doing this equalizes the concentrations on both sides of the membrane. Our question throughout the experiment was; What effects do the different concentrations of sucrose have on the rate of osmosis? The hypothesis was; If the solute concentrations do effect the rate of osmosis,…

The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo…
