Steric Hyndrance Effects on Esters

Electronegative and Steric Hindrance Effects on Synthesized Esters By Katherine Edmonds Introduction: Esters are made when an acid and an alcohol are mixed. The reaction causes the oxygen and hydrogen atoms to pair off, forming H20, leaving the rest of the compound to form the ester. The theory is that if a more electronegative element was added to the compound, it could increase the electronegativity in the whole molecule, and the ester could form more …

…of the aqueous layer discarded as possible. The mixture was then rinsed using 20 mL NaHCO3, and the pressure routinely released. The aqueous layer was tested with lithmus paper. Since it yielded a pH of 1, there was no need to repeat the NaHCO3. A 25 mL H2O rinse was done again. The mixture was dried over MgSO4. The mixture was distilled and had a 63.39% yield. Density of 0.891, and a b.p. of 1008ºC. NMR (CDCl3,300MgHz)
