Question

In this experiment, an intense color change will indicate a reaction with ferric chloride. You will formulate a hypothesis based on your observations of what happens when you add ferric acid to tubes 1, 2, and 3 as compared to tube 8 (your control). Your hypothesis should describe what type of compounds you think react with ferric chloride, and allow you to predict what will happen with the other tubes. Let's pretend tubes 1 (methyl salicylate) and 3 (aspirin) changed color, and tube 2 (salicylic acid) looked just like tube 8. What would be an example of a good hypothesis? Select any answers that apply O Ferric chloride reacts with benzene rings. Ferric chloride reacts with compounds that contain both a benzene and an ester Ferric chloride doesn't react with carboxylic acids. Ferric chloride reacts with some organic compounds. Ferric chloride reacts with tubes 1 and 3. Ferric chloride reacts with esters.

Explanation / Answer

Ans: Ferric chloride react with tubes 1 and 3.

Logic: tube 1 and 3 react with ferric chloride whereas, 2 and 8 have same color,

the tube 8 is control ( which does not react with ferric chloride ) therefore in 2 compound also does not react with ferric chloride.
