Answer:
- CH₃ - CH - COOH

OH
- The developed structural formula is also attached.
Explanation:
The IUPAC name, <em>2-hydroxypropanoic acid</em>, lets you predict the structural formula for <em>lactic acid</em>.
- <em>2-hydroxy</em> means that there is a OH functional group attached to the second carbon atom of the chain.
- <em>Propan</em> prefix means that the molecule has 3 carbon atoms.
- <em>oic</em> suffix means that it is a carboxylic acid, this is it contains the COOH functional group.
Hence, in conclusion the structural form of lactic acid is:
- C³H₃ - C²H - C¹OOH
|
OH
I used the superscripts just to show the number of the carbon atom in the chain.
The formal structural formula does not contain such superscripts it is just:
- CH₃ - CH - COOH
|
OH
A more developed structural formula will show the distribution of the atoms in the space. I have also attached a picture with the developes structural formula.
