Question

A mixture of compounds containing diethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as follows: Step 1: Concentrated HCl is added followed by draining the aqueous layer. Step 2: Dilute NaOH is added to the organic layer followed by draining the aqueous layer. Step 3: Concentrated NaOH is added to the organic layer followed by draining the aqueous layer. Which compound would you expect to be extracted into the aqueous layer after the addition of dilute HCl, step 1? Group of answer choices

Answer:

The correct option is ammonia

Step-by-step explanation:

The mixture contains two base compound which are

ammonia,

and diethylamine

Now the addition of HCl which is a strong acid in step 1 will cause the protonation of the two base compound , which makes the soluble hence resulting in them being extracted to the aqueous layer as represented in below

`NH_3 + HCl\to NH_4 ^(+) + Cl^-`

and

`(CH 3CH 2) 2NH + HCl \to (CH 3CH 2) 2NH_2^(+) + Cl`
