Bioinorganic Coordination Chemistry


This experiment uses H2TTP made during the last lab and hydrated
copper (II) acetate to convert the H2TTP to Cu(TTP). The reaction
proceeds by being refluxed for 30 minutes. The final product is a
non-iridescent purple color, unlike the vivid, shimmering purple color
of the starting H2TTP.

Introduction

Thin layer chromatography, or TLC, is used as a prerequisite for
column chromatography. When performing types of chromatography, like
TLC, the polarity of solvents is extremely important. This lab uses
TLC plates, five solvents (hexane, toluene, ethyl acetate,
dichloromethane, and acetone), and small evaporating dishes to
determine which solvent would be best to use in column chromatography.
The least polar solvent is hexane, which has a polarity index of 0.1.
Toluene has a polarity index of 2.4, while ethyl acetate’s is almost
twice that at 4.4. By comparing the polarity indexes, you can tell
what solvent will separate your dots of product on your TLC plates the
best (Skoog 761).

Experimental Section

The equipment needed for this experiment is as following: 100 mL round
bottom flask, stir bar, water condenser, hot plate, UV light, Pasteur
pipet, ice bath, separatory funnel, rotary evaporator, evaporating
dish, cotton for filtering, and UV-vis spectrometer.

The chemicals required are: 0.1 g. of H2TTP made previously, 20 mL
N,N-dimethylformamide, 0.16 g. hydrated copper acetate, distilled
water, 75 mL dichloromethane, hexane, toluene, ethyl acetate,
dichloromethane, and acetone for TLC plates.

Procedure

1. Measure out 0.1 g. of the H2TTP made previously into a 100 mL

...aporates off the gel leaving open sites
where polar molecules can bond. When you let silica gel out in the
open, it will collect water molecules on it. Compounds would elute
faster down a column that has been heated at 150 degrees for 8 hours
because the gel would be dry.

3. A mixture of cis and trans isomers of the neutral complex Cr(CO)4[P(C6H5]2
is loaded onto a silica gel and eluted with CHCl3. Which isomer would
elute first, and
why?
The trans isomer would elute first.

Essay on Coordination Chemistry of 3D Transition Metals - ... 1.2 Coordination chemistry of 3d-transition metals Coordination chemistry involving 3d-transition elements are important because they are used in catalysis, molecular electronics, magnetism, photochemistry and in biological systems. Due to presence of partially filled ‘d’ orbital, comparatively smaller size of metal ions, variable oxidation state and high ionic charges they have tendency to form stable complexes with varieties of organic and inorganic compounds. The complexes formed have various coordination geometries, colours and have unusual magnetic and spectroscopic properties....   [tags: chemistry of metal complexes] 988 words

Ring Main System • To setting relay, the same method is used for both ring and radial system. However, the circuit must be opened, start at the source point to form a two radial circuit before setting the relay. First, followed the clockwise. • The relay setting start with R1 and the concept same like radial system. Second, followed the anticlockwise and the system will form a radial circuit....   [tags: operational restrictions, coordination]

Surface Chemistry of Silica Essay - In order to gain strong insight into the surface chemistry of silica we have perform a thorough literature search. Our goal is to identify the pioneer research performed on silica and silica supported catalyst. Particular interest lies in silica-water-cobalt and silica-alcohol-cobalt systems. This study is both on macro and micro level so that a complete theoretical base can be established. From this theoretical knowledge, key areas to look upon will be identified and a design of experiments will be established....   [tags: Chemistry] 1273 words

Alpha radiation/emission - Alpha particles are the nuclei of a Helium atom 42He. Consisting of two protons and two neutrons, positively charged. The nuclei are ejected from heavy, unstable nuclei so as to remove excess protons and neutrons. However, the formed nuclei may still be radioactive in which even further decay will occur. Alpha emissions occur in nuclei with atomic numbers greater than 83....   [tags: Chemistry]

When the odorants ( smell molecules) enters the nose it dissolves in mucus and sinks down to the olfactory epithelium which is made of millions of tiny receptor neurons. Cilia, a protruding knob that is in the middle of the neurons,receives the odorant and sends it directly to the part of the brain called the olfactory bulb. In fact cilia is the only part of the brain that is visible outside of the skull(The Science of Taste and Smell)....   [tags: Chemistry Essays]

Chemistry before Technology: Alchemy Essay - ... According to the New York Times article “The Magical Origins of Modern Chemistry” alchemy was a philosophy and practice that sought to understand the nature of matter. Because of the alchemist they were able to make porcelain, pigments, perfumes, gunpowder, and pharmaceuticals. Before technology was brought into chemistry it took longer for scientist to discover certain items and chemical compounds and it took them longer to figure out how to do certain things.
