Why did you not wash the crude t, Because I think that t-pentyl alcohol and sodium chloride will be produced t-penyl alcohol is also known as tert-amyl alcohol or 2-methyl-2-butanolSynthesis of T, The top layer and less dense is the organic layer, the t-pentyl chloride and the bottom layer is the aqueous layer The purpose of shaking vigourously is to make sure that the 2 liquids mix properly, giving us the desired product t-pentyl chloride Then we wash the organic layer with water T-pentyl chloride is insoluble in water, so it wont beT Pentyl Chloride Lab Report Essay, The t-pentyl chloride (d _ 0865 g/mL) should be the top layer, but be sure to verify this by adding a few dropsof water The water should dissolve in the lower (aqueous) layer Drain and discard the lower layer Extraction The operations in this paragraph should be done as rapidly as possiblebecause the t-pentyl chloride is unstable in,Organic CHem help? Tert, Jun 14, 2009· Ideally every single molecule of t-pentanol would be converted to a molecule of t-pentyl chloride; in other words, you would end up with 002269 mol t-pentyl chloride To determine how much a sample of 002269 mol t-pentyl chloride weighs, you use its molecular weight, which is 1065935Experiment 23B Synthesis of t, Why did you use aqueous sodium bicarbonate (a weak base, baking soda) to wash the crude t-pentyl chloride?
