Question Molecular Geometries – A Molecular Drawing and Modeling Experience style=”color:rgb(86,90,92);”> linkI choose TNT molecule compound and need help in researching the chemical’s history, structure and molecule builder by using the theories of VSEPR atom hybridization to visualize the structure. Instruction: a. TNT chemical structure and history: Who discovered/synthesized it? What is its systematic name? From where was its common name derived?What is its use, if any? Offer fun and interesting/obscure factsb. On a blank piece of paper, hand draw the TNT molecule. Expand any condensed bonds, Make sure each element has the correct number of atoms by adding in hydrogen atoms where necessary. Determine the molecular formula by counting atoms. Include this on the drawingLabel each atom’s hybridization using a specific color for each hybridization state. These may be sp, sp2, sp3, sp3d, or sp3d2Use a specific color for sigma bonds, trace each sigma bond in that color. Use a specific color for pi bonds, trace each pi bond in that color. Label the approximate value of all bond angles.Make Key reference of the colors you used and what they stand for and include on this sheet.
