What are the units used for the ideal gas law? They are employed in the paper, plastic, and rubber industries. Correspondence to The article is published in the original. Morrison, R.T. and Boyd, R.N., Organic Chemistry, Englewood Cliffs, NJ Prentice Hall, 1992. [11][12] The International Agency for Research on Cancer (IARC) originally classified saccharin in Group 2B ("possibly carcinogenic to humans") based on the rat studies, but downgraded it to Group 3 ("not classifiable as to the carcinogenicity to humans") upon review of the subsequent research. Those monosaccharides that contain an aldehyde functional group are called aldoses; those containing a ketone functional group on the second carbon atom are ketoses.
