Answers:

Sodium naphthoxide will be found in the aqueous layer Naphthalene will be found in aqueous layer sodium bicarbonate will be found in the aqueous layer Very small ammount of benzoic acid will be found in the aqueous layer Sodium benzoate will be found in the aqueous layer Sodium naphthoxide and sodium benzoate will be found in the aqueous layer

Explanation / Answer

1) Diethyl ether solution of naphthalene and naphthol will be extracted with 20 ml portion of 1.25M aqueous sodium bicarbonate- sodium bicarbonate will be found in the aqueous layer.

2)  Diethyl ether solution of naphthalene, benzoic acid, and naphthol is extracted with 20 ml portion of water- very small amount of benzoic acis will be found in the aqueous layer.

3) Diethyl ether solution of naphthalene, benzoic acid, and naphthol is extracted with 20 ml portion of 2.5M aqueous sodium hydroxide- Sodium napthoxide and sodium benzoate wil be found in the aqueous layer

4) Diethyl ether solution of naphthalene and naphthol is extracted with 20 ml portion of 2.5M aqueous sodium hydroxide-  Sodium napthoxide wil be found in the aqueous layer.

5) Diethyl ether solution of naphthalene, benzoic acid, and naphthol is extracted with 20 ml portion of 1.25M aqueous sodium bicarbonate- sodium benzoate will be found in the aqueous layer.
