Answer #1

You should leave the separatory funnel unstopped during the addition of HCl to t-pentylalcohol.

Since,  t-pentylalcohol. is a tertiary alcohol, and reacts if it is shaken with concentrated HCl at room temperature. A tertiary halogenoalkane ( t-pentylchloride) is formed.

When a tertiary alcohol is treated with strong hydrochloric acid, an immediate exothermic reaction occurs and a distinct layer of the tertiary chloride separates. The heat generated due to exothermic reaction should be disspersed by keeping it open to cool it down. And if the separatory funnel is closed it might burst.

A sample of 4-toluic acid is contaminated with a small amount of sand & toluene. Using active extraction (changing the polarity by addition of certain chemicals) & a gravity filtration to remove a component, describe how you would obtain pure 4-toluic acid in its solid form from this mixture. Note that use of an organic solvent like ether should be used initially, & then any other procedures, including use of a separatory funnel is required.

Organic Chemistry Lab: Separation and Identification of Unknown Compounds Explain why the addition of acid (3 M HCl(aq)) or base (3 M NaOH(aq)) will not separate the neutral compound into the aqueous layer? List four distinct impurities found in the isolated acid. Assume that the procedure was followed exactly and that there was no human error. About the procedure: the acid was isolated via Vacuum Filtration after precipitated with 12M HCl and cooled in an ice-water bath.
