Suppose you are performing an extraction procedure with a carboxylic acid, like a benzoic or toluic acid Which layer should contain the carboxylic acid in a two-layer mixture of water and an organic solvent, like diethyl ether? A. The organic layer B. The aqueous layer C. Neither layer

The correct answer is option A, that is, the organic layer.

Explanation:

One knows that non-polar solvent dissolves non-polar substances and the polar solvent dissolves polar substances, that is, like dissolved like. The toluic acid or benzoic acid refers to the carboxylic acids, which are non-polar or are very less polar in characteristics.  

Therefore, they possess the tendency to remain in the organic solvent, which is non-polar like diethyl ether. The toluic acid's or benzoic acid's non-polar characteristic is because of the existence of huge hydrophobic rings of benzene. Hence, the correct answer is option A, that is, the organic layer.  

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
