Describe how acetone is an example of functional groups - CORRECT ANSWER✅✅Acetone is another
standard organic compound with the functional group of a ketone (CH3COCH3)
Describe how vinegar is an example of functional groups - CORRECT ANSWER✅✅Vinegar is a standard
organic compound that contains acetic acid compound which has the functional group of a carboxylic
acid (CH3CHOOH).
The collection of atoms in the COOH gives chemical activity in the form of acid/base reactions due to the
polarity of the oxygen presence
