Sodium bicarbonate is then used to wash the crude t-pentyl chloride. What is the purpose of this wash and why would it be bad to wash with sodium hydroxide?
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 be

Because the boiling point of t-pentyl chloride is lower than that of t-pentanol, the vapor that forms over the crude product solution will contain a larger fraction of t-pentyl chloride as compared to the solution from which the vapor formed. As the vapor condenses in the fractionating column a new solution is formed.
The reaction took place with t-pentyl alcohol and HCL to produce t-pentyl chloride. Aqueous sodium bicarbonate was used to wash the crude t-pentyl chloride (a) What was the purpose of this wash? Give
1. a) Aqueous sodium bicarbonate was used to wash the crude t-pentyl chloride in order to eliminate the polar impurities; mainly to get rid of the excess of HCL. Equation: HCl → NaCl + H2O + CO2.
In the second experiment, a tertiary alkyl halide t-pentyl chloride (t-amyl chloride) is prepared as shown in Equation 2. [2] These reactions provide an interesting contrast in mechanisms. The n-butyl bromide synthesis proceeds by an S N2 mechanism, whereas t-pentyl chlo-ride is prepared by an S N1 reaction.
t-Pentyl Chloride is a compound that is created through an SN1 nucleophilic substitution reaction in addition with Hydrogen Chloride in order to isolate the product. A variety of procedural techniques were utilized during the experiment including extraction, washing liquids, drying liquids, gravity filtration, and simple distillation.

Aqueous sodium bicarbonate was used to wash the crude n-butyl bromide. a. What was the purpose of this wash? Give equations. b. Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? 5. Look up the density of n-butyl chloride (1-chlorobutane). Assume that this alkyl halide was prepared instead of the bromide.
Sodium chloride removed the impurities from the desired compound; in this case, water (Long Island University, 2010). Sodium bicarbonate, being a weak base, neutralized the remaining hydrochloric acid (Univeristy of California Los Angeles, 2013). Carbon dioxide gas is given off when it reacts with HCl.
In the preparation of t-pentyl chloride from t-pentyl alcohol, trace amount of hydrochloric acid will not react. To remove hydrochloric acid from the reaction mixture, crude t-pentyl chloride is washed with sodium bicarbonate. The chemical reaction is as follows: Chapter 23, Problem 1PCQ is solved.
