Question

A student used the same protocol as in the lab manual to extract benzoic acid, phenol, and naphthalene. Below are the steps he took:

**Step 1** – Dissolve all three in 15 ml ether and place in a separatory funnel.

**Step 2** – Add 15 ml of sodium carbonate and mix well.

**Step 3** – Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate.

**Step 4** – Add 15 ml of sodium hydroxide to the ether layer and mix.

**Step 5** – Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate.

**Step 6** – Dry the ether layer and collect the solid that is left.

Expert Solution

Step 1

Presentation is called as which do not dissolve in water

Step 3 ) naphthalene will form precipitate because snow land carboxylic acid is acidic so they will not react with hydrochloric acid which is also an acid

Step4)when any which is inserted then carboxylic acid will react with any veg because carboxylic acid is more acidic than phenol so benzoic acid will form precipitate

Step by step
