Heat the water on an oven burner or place it in sunlight for several days to evaporate the water out of the pan. Allow the water to evaporate away and you will be left with the food coloring remaining in the pan.

Draw the major organic product that is expected when cyclopentanecarboxylic acid is treated with each of the following reagents:

son4ous [18]

Answer:

a. Sodium cyclopentanecarboxylate

b. No reaction

Explanation:

In this case, in the cyclopentanecarboxylic acid we have a carboxylic acid functional group. Therefore we have an "acid". The acids by definition have the ability to produce hydronium ions ( $H^+$ ).

With this in mind, for molecule a. we will have an acid-base reaction, because NaOH is a base. When we put together an acid and a base we will have as products a salt and water. In this case, the products are Sodium cyclopentanecarboxylate (the salt) and water.

For the second molecule, we have the hydronium ion ( $H^+$ ). This ion can not react with an acid. Because, the acid will produce the hydronium ion also, so a reaction between these compounds is not possible.

See figure 1

I hope it helps!
