The document discusses and ranks the polarity of several compounds from least polar to most polar. Naproxen sodium is the most polar due to being ionic. Ibuprofen is the least polar with only a polar carboxylic acid group and nonpolar structures. The other compounds have varying numbers of polar groups like hydroxyl, carbonyl, and amide groups attached to mostly nonpolar ring structures.
Naproxen sodium is very polar because it is ionic.pdf
1. Naproxen sodium is very polar because it is ionic (sodium ion). Naproxen itself
(without the sodium) is only slightly polar because it has a -COOH group (which is extremely
polar) and 2 nonpolar rings. Ibuprofen is only slightly polar because it has a -COOH group but it
has a nonpolar ring and nonpolar side chains. Salicylamide is very polar because it has a -
CONH2 polar group and a -OH polar group, and only a nonpolar ring. Caffeine is moderately
polar because it has 2 =O polar groups but it has 2 nonpolar rings. Acetaminophen is very polar
because it has a -CONH polar group and a -OH polar group, and only a nonpolar ring.
Acetylsalicylic acid is very polar because it has a -COO polar group and a -COOH polar group,
and only a nonpolar ring. Rank (least polar to most polar): ibuprofen
