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…

I am a mixture. A mixture of the habits I have developed from those closest to me, the cultures of my ancestors and my parents, along with interests that are ever growing. Among these there are a few that were instrumental in the discovery of both myself and what my future held in store. For the past 17 years I have grown up in a household that was much larger than one roof could cover. I was raised by my parents, my tías, and my teachers, and from each have learned something valuable. Through…

In this experiment, identifying the acids, bases, or neutrality of the unknown substance in a specific set are used to find the actual substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver…

cigarettes and cigars. Tabacco may remain in clothes, furniture, curtains, cars lining, hair and other substances for long lengths of time. Cigarettes may also stain teeth, skin, ceilings, cars and other things that people do not want stained. This can cause security deposits to be lost and people to believe that you are unhygenic. Vaping, on the other hand, does not leave odors or stains. Because the chemicals used in vaporizors do not produce tar and are not odorous, these common complaints…

In this week’s reflection video, I, learned about the weapon printing design done by the process of hydro-graphics. In the video a rifle stock is used with a Dip Wizard hydrographic kit to add a camouflage pattern. The Dip Wizard’s Kit just like other hydrographic kits uses a technique of applying a printed pattern such as; camouflage or any other pattern to a 3-dimensional object. This process goes by the terms; hydro-graphics, hydro-dipping, image transferring, immersion and water print…

A glow stick is a small plastic tube with chemicals inside it. When When you snap a glow stick and hear it crack it gives off a temporary glow. As you snap the glow stick and hear it crack. Chemicals inside the glow sticks starts to mix together. This is a process call chemiluminescence. Chemiluminescence is a process where light is produced by a chemical reaction. Instead of using an electrical source. An example of this would be if go outside during a fall night and see a firefly glowing…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

the cis isomer. This ratio was determined by looking at the two singlets in the spectra RM-09-1 representing the protons on alkene double bond. The singlets in RM-09-1 were found at 7.11 ppm and 6.59 ppm. The reported values, found on SDBS, for the chemical shifts of these singlets were 6.57 ppm for (Z)-stilbene and 7.15 ppm for (E)-stilbene. These peaks also determined the ratio of isomers for the second and third fractions as well. In the spectra RM-09-2, the ratio was determined to be 4:3.…

The expression "SN1" is the abbreviation of "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:…

The process of synthesizing a drug is very hard to completely control but can be managed through the use of several organic chemistry principles. Chemical synthesis can be sped up by using catalysts to reduce the activation energy required to break and reform the bonds of molecules. Pseudoephedrine is a great example to show how factors such as polarity, functional groups and bonding sites can be used…
