Question

How expensive are Grignard reagents?

Answer 1

Just as an example, phenylmagnesium bromide (PhMgBr) costs, for a 3.0 M solution: $39.40 for 50 mL; $48.50 for 100 mL; and $186.50 for 800 mL from the Aldrich catalog.  (Note that since you're paying for specialized packaging, it's not proportional to the amount of PhMgBr).

BE HAPPY ^_^

Answer 2

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
