In the early days of organic chemistry, scientists had only a few techniques available to them for the analysis of compounds. these included smell, taste, color, and physical state (gas, liquid, or solid). with this in mind, suggest how they could differentiate between the compounds in the following pairs. you will need to research the properties of the different chemicals using books and the internet. share your answers in a post with others in your group. comment on the posts of at least two other students - have they correctly identified tests that would allow them to differentiate the compounds? benzonitrile and benzoic acid ethanoic (acetic) acid and ethanol sodium ethanoate (sodium acetate) and glucose methyl butanoate and ethyl butanoate
