(i)There is an aryl substituent at C-2 of propanoic acid in ibuprofen. This aryl substituent is abenzene ring bearing an isobutyl group at the para position.(j)Benzenecarboxylic acid is the systematic name for benzoic acid. Salicylic acidis a derivativeof benzoic acid bearing a hydroxyl group at the position ortho to the carboxyl.19.14(a)The carboxylic acid contains a linear chain of eight carbon atoms. The parent alkane is octane,and so the systematic name of CH3(CH2)6CO2H is octanoic acid.(b)The compound shown is the potassium salt of octanoic acid. It is potassium octanoate.(c)The presence of a double bond in CH2?CH(CH2)5CO2H is indicated by the ending -enoicacid.Numbering of the chain begins with the carboxylic acid, and so the double bond is be-tween C-7 and C-8. The compound is 7-octenoic acid.(d)Stereochemistry is systematically described by the E–Znotation. Here, the double bond be-tween C-6 and C-7 in octenoic acid has the Zconfguration; the higher ranked substituents areon the same side.(e)A dicarboxylic acid is named as a
