An alternative and more covenient method involves the in situ generation oh hydrobromic acid by the addition of concentrated sulphuric acid to an aqueous soluition sodium bromide. From the calculation , the percatage yielid for this experiment is In the second step shown in Figure 3, the carbocation will then obtain a nucleophile and the reaction rate will depend on the concentration of the alkyl halide, which makes it a first order mechanism. The filter funnel is clammed upside down at the stem so that its mouth just touches the surface of the water contained in a beaker. What is the purpose of this wash? Being a strong synthesis, this gas will cause damage to lungs when inhaled and will certainly sting from. When conduct the experiment, we need to wear gloves while doing an experiment because 1-butanol and 1-bromobutane are. However, some alkyl halides are also a danger Shikonin biosynthesis of melanin the substances.

Your apparatus must be vented appropriately, directly into the air vent above your bench see Figure 7. Determine the weight of your material and calculate the percent yield. The leaving group is is a group of atom which depart with the electron pair used to bond them with the substrate. A few boiling stone were added and the distillation was started.

The percent yield of the final product is determined after the synthesis. The heat was turned off when the reflux is over and allow the condensate in the condenser to drain back into the flask. Think what is in the aqueous solution. The filter funnel is clammed upside down at the stem so that its mouth just touches the surface of the water contained in a beaker. When all of the NaBr has been added use your spatula to remove any solid material that is adhering to the inside of the ground glass joint of your mL round bottom flask. First, we react the alcohol with p-toluenesulfonyl chloride which will convert OH- into sulfonic acid ester to react with sodium bromide to produce 1-bromobutane.
