Question

Why dont we write CH³CO²H in place of CH³COOH (acetic acid)??​

Answer 1

The chemical formula is actually neither of the two: it would be C 2 H 4 O 2 . What you show here is a condensed structural formula: it tries to convey not only the atomic composition, but also the way the atoms are connected. This only works for relatively simple organic compounds. The “COOH” is the conventional way in this formalism to represent an acid group. It represents better than CO 2 H that the two oxygens are different, and that the H is connected to one of the oxygens.

Answer 2

Answer:

Acetic acid, also known as ethanoic acid and methanecarboxylic acid, is a colorless liquid that has a strong and distinct pungent and sour smell. Its chemical formula is C2H4O2: it has two carbon (C) atoms, four hydrogen (H) atoms and two oxygen (O) atoms. Because it has a carbon in its chemical formula, it is an organic compound. Its chemical formula can be written multiple ways, as shown here:

C2H4O2

CH3COOH

CH3CO2H

Now that we know the chemical formula of acetic acid, let's talk about its chemical structure. Its chemical structure is shown in the following illustration. Here, we can see two ways to draw its chemical structure (see video). On the left (1), all the carbon, hydrogen and oxygen atoms and how they are bonded to each other are shown. On the right (2), instead of writing the carbon atom, it is represented by an edge or bend in the line, and the hydrogen atoms attached to the first carbon on the left are not shown..
