What is the MOST important safety concern when washing the organic layer of this reaction with sodium bicarbonate during liquid-liquid extraction? Group of answer choices
-Sodium carbonate gas builds up in the separatory funnel and can cause the glass to become pressurized and explode. -Carbon dioxide is given off during the sodium bicarbonate wash.
-Carbon dioxide gas builds up in the separatory funnel and can cause the glass to become pressurized and explode.
-Carbon dioxide liquid builds up in the separatory funnel and can cause the volume of the sep. funnel to exceed 2/3.
-Sodium carbonate is given off during the sodium bicarbonate wash.
-Solid sodium carbonate particles build up in the separatory funnel that can scratch the glass and cause an explosion. -Water vapour forms and builds up in the separatory funnel and can cause the glass to become pressurized and explode.
-Water is given off during the sodium bicarbonate wash.

Procedure Esterification Each group will be assigned an unknown alcohol by the instructor. Record the unknown number and then add the contents of the vial (25 mmol of alcohol) to a 50 mL round bottom flask with a stir bar Then add 2.75 mL (approx. 50 mmol) of acetic acid followed by 0.25 mL of concentrated sulfuric acid Add a reflux condenser then reflux the mixture in a sand bath with stirring for one hour....

MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...

Just Answer Question 5
Synthesis of 2-chloro-2-methylbutane (literature version) Concentrated aqueous hydrochloric acid (HCI, 3.3 equivalents) was slowly added to 2-methyl-2-butanol (1.0 equivalents) in a 100 mL round bottom flask with stirring. The reaction was stirred for 15 minutes at room temperature. Upon completion, the reaction mixture was transferred to a 60 mL separatory funnel and the aqueous layer was removed. The organic layer (i.e. the product) was successively washed with: (1) saturated aqueous NaCl (brine), (2) saturated aqueous NaHCO,...
