Question

Hello, if you answer this question quickly, I will immediately give a thumbs up on your answer!

The organic layer is washed using saturated sodium chloride by shaking the separatory funnel containing the solution. It allows water molecules to move from the organic layer to the aqueous layer (refer to steps 4 and 7 from Part A of the procedure). True or False? * I'm confused about this question because by shaking and washed was bolded. But we don't shake it, we invert and vent? Or am I overthinking it?

This experiment is completed over two lab periods. In the first lab period, the initial reaction mixture (pale yellow color) is placed in an Erlenmeyer flask and allowed to stir for about 15-minutes until the yellow color subsides. Which of the following is placed in the initial reaction mixture? Select all that applies:

-12 mL of acetone

-10 mL of DI water

-3.8 mL of cyclohexene

-20 mL of diethyl ether

-20 mL of saturated sodium chloride

-a dime sized portion of anhydrous sodium sulfate

-7.4 g of N-bromosuccidimide (NBS)

Consider the reaction scheme for the two step syntesis of epoxycyclohexane from cyclohexene to match each of the following:

Starting Material (step 1)

Reagent (bromine source)

Reagent (hydroxide source)

Reaction intermediate (starting material of step 2)

Product

Reagent (deprotonates the alcohol group in 2-bromocyclohexanol)

Answer 1

The organic layer is washed using saturated sodium chloride by shaking the separatory funnel containing the solution. It allows water molecules to move from the organic layer to the aqueous layer : True

(you are overthinking it, it is simple statement , as during separation will shake solutions in separatory funnel for better outcomes). ( The organic layer is separated from the aqueous layer : Any water present in organic layer can be removed by usig drying agent such as NaCl, wash it with saturated NaCl solution before adding drying agent. The NaCl solution transfers the water from the organic layer to the aqueous layer. )
