We go ahead and add the -yl in and then the chloride like that. Therefore, it has the formula R C O â, where R represents an alkyl group that is linked to the carbon atom of the group by a single bond. With carbon nucleophiles such as Grignard reagents, acyl chlorides generally react first to the ketone and then with a second equivalent to the tertiary alcohol. To ensure the hot solution would be saturated. The IUPAC name for the product isN-ethyl propanamide, as it is formed from ethanamine and propanoyl chloride. The presence of the chlorine on the carbonyl carbon makes it a very good electrophile, since both the oxygen and chlorine are strongly electron withdrawing, giving the carbon a large partial positive charge.
