Fracking is a contemporary method of extracting oils and gases that has become quite the vexation for many societies around the world. Fracking is the process in which liquid is injected at a high-pressure rate into different forms of rocks in order to forcefully open exiting fissures in order to extract oils or gases. During this process‚ water‚ sand and chemicals are inserted into the rock at high pressure; this part of the process allows the gas to flow to the head of the well and outward. Geological

Trinitrotoluene‚ TNT‚ or 2‚4‚6-trinitrotoluene‚ is a nitro chemical compound with the formula C₆H₂(NO₂)₃CH₃. TNT is a yellow-colored solid and contains in its structure three NO2 groups and one –CH3 group all bonded to carbon atoms on the aromatic ring (Juhasz and Naidu 2007‚ Pichtel 2012). Oxygen and nitrogen are the two highly electronegative elements where oxygen possesses the highest electro-negativity. Subsequently‚ the polarized N–O bonds within the nitro groups makes them easily reducible

Introduction: The purpose of this experiment is to use sodium borohydride to reduce benzil. However‚ stereochemistry allows for five possible products. If only one carbonyl group is reduced during the reaction a racemic mixture of benzoin will be the product that is produced. After the first reduction a chiral center forms causing the second reduction to occur from only one side of the ketone. Depending on which side the second reduction take place there are three possible products including: a racemic

In the first part of this experiment acetic anhydride was used to prepare acetanilide which could then be readily brominated to form a mono-brominated product‚ with the bromine positioned at either the ortho‚ meta or para position on the aromatic ring. Acetic anhydride is very reactive towards nucleophiles and this reactivity is the result of the difference in electronegativities of the carbon and oxygen atoms that are bonded in acetic anhydride. This difference in electronegativities causes one
