Experiment ( preparation of tert-butyl chloride )

1- what is the purpose of washing tert-butyl chloride with saturated NaCl solution

2- describe a way to distinguish between an aqueous layer and an organic layer in separatory funnel.

Expert Solution

1. Tert-butyl chloride is prepared from tert-butanol and HCl, after reaction completion the inorganic impurity are removed by washing with water in repeating funnel. The seprating funnel will have two layers one is organic layer and other is aqueous layer. The purpose of adding aqueous sodium chloride is to remove the water from wet organic layer, the role of sodium chloride is drying agent.

2. In organic layer purified compound will be there

In aqueous layer inorganic byproduct and impurity will be available.

Mostly aqueous layer is more denser than organic layer therefore it will be at bottom of the seprating funnel

Organic layer is less denser than aqueous layer therefore it will be at top of the seprating funnel

Organic compounds are mostly insoluble in water therefore it will be organic layer

Inorganic byproduct and inorganic impurity are highly soluble in water therefore it will be in aqueous layer.

In this experiment 2.0 mL of tert-butyl chloride (TBC) will be used. The density of TBC is 0.847 g/mL and its molar mass is 92.57 g/mol. (a) Calculate the weight and the number of moles of TBC to be used. (b) Calculate the number of moles of HCl that would be produced by the complete hydrolysis of the 2.0 mL of TBC. (c) Calculate the volume of 0.400 M NaOH solution required to neutralize the total amount of HCl produced...

Friedel-Crafts alkylation of anisole (PhOCH3) with tert-butyl chloride [(CH3)3CCl] and AlCl3 gives mostly the para-substituted product. Explain this outcome by showing the complete step wise mechanisms for para and meta positions using the curved arrow notation. The mechanisms must include the formation of the electrophile, attack of the electrophile at the meta and para positions, as well as all stabilizing resonances of the arenium ions that are formed and their relative stability, and the final substitution products.

when the acid constants of tert-butyl alcohol and methanol are determined in the gas phase, tertiary alcohol is found to be a stronger acid. This result is opposite in aqueous medium. Consider the effects of solvation to explain these different results.
