Question

Write the structures of the following : 3-chloro butan-1-oic acid​

Answer 1

Answer:

Although a fairly simple question, incorrect nomenclature is used. -one is a suffix (and used when the ketone group is the highest priority) and not a prefix for ketone. Also, there is the presence of a carboxylic acid group which is automatically given the highest priority. You will now number your carbon from there.

The proper way to write its name would be:

3-oxobutanoic acid

And not 'butan-3-one-1-oic acid' as written as I write this. Now, you can easily draw the structure. The best way is to read it backwards as it helps you make the parent chain first and then the substituents:

butanoic acid | 3-oxo
