Question

Assume that benzene is insoluble in water. The normal boiling points of benzene
and water are 80.1 and 100°C respectively. At a pressure of 1 atm, the boiling point
of a mixture of benzene and water is
​

Answer 1

Explanation:

In the compound both ketone and the carboxylic group is present. Priority is given to carboxylic group at C-1, and the ketonic group at C-3 is treated as a substituent. Thus the prefix used is "keto" and the suffix used is "oic acid".

Thus IUPAC name is 3-ketobutanoic acid
