Solution

Butanoic acid, also known as butyric acid, is a carboxylic acid with the structural formula C3H7COOH. Here's a step-by-step guide on how to draw it:

  1. Start by drawing four carbon atoms in a row (or a chain), as the prefix 'but' in butanoic acid indicates there are four carbon atoms. Label them as C.

  2. Connect these carbon atoms with single lines (or single bonds). Each line represents a single covalent bond.

  3. Now, at one end of the carbon chain, draw a 'C' (carbon) connected to an 'O' (oxygen) with a double bond, and another 'O' (oxygen) connected to the same 'C' (carbon) with a single bond. This is the carboxyl group (-COOH) which is characteristic of carboxylic acids.

  4. Finally, fill in the remaining bonds of the carbon atoms with hydrogen atoms (H). Each carbon atom forms four bonds in total. The end carbon in the chain (not connected to the carboxyl group) should have three hydrogen atoms, while the other two carbon atoms in the middle of the chain should each have two hydrogen atoms.

  5. The final structure should look like this:

    H H H O | | | || H--C--C--C--C | | | | H H H H

This is the structure of butanoic acid.
