- An acid (A) containing only C, H, and O had a NE of 103 ± 1. It gave a negative test with phenylhydrazine.
Treatment with sulfuric acid converted it to a new acid (B) which decolorized permanganate and bromine solutions
and had a NE of 87 ± 1. The original acid (A) was transformed by hypoiodite to iodoform and a new acid (C), the
NE of which was 52 ± 1.
- An acid whose NE was 166 was unaffected by bromine in carbon tetrachloride but gave a positive iodoform test.
- An unknown weighing 6.59 g was placed in a Dumas apparatus and vaporized at 119.3 oC to produce a
gas whose volume was 1.98 L. The compound was soluble in 5% HCl solution. When treated with benzenesulfonyl chloride
and base a solid formed, which remained after acidification.
- An optically active acid, having a molecular weight of 98, decolorized bromine in carbon tetrachloride.
