What is the chemical formula for an alkane with 12 carbon atoms?
  7, C = 15 in tables 4 and 5 and at .v = ~5, C = 13 and 15 in table 5 are produced apparently 574 Annals New York Academy of Sciences by nonbasic cyclic nitrogen compounds. These compounds are slightly more polar than alkanes and are more concentrated in the carbon tetrachloride eluate (table 5) than in the -heptane eluate (table 4). In table 4, the peaks at .v = 6 and 7, C = 16 are larger than those of homologous ions at C 13, this suggests that the nitrogen ions may have obscured the ‘ …
