Problem 14.30 How many rings are present in each of the following compounds? Each consumes 2 mol of hydrogen on catalytic hydrogenation. (a) C₁0H18 (b) CgHg (c) C8HgCl₂ (d) CgH₂O (e) CgH1002 (f) CgH,CIO (g) C3H5N (h) C₂H5N Sample Solution (a) The molecular formula C₁0H₁8 contains four fewer hydrogens than the alkane having the same number of carbon atoms (C₁0H22). Therefore, the index of hydrogen deficiency of this compound is 2. Because it consumes two molar equivalents of hydrogen on catalytic hydrogenation, it must have either a triple bond or two double bonds and no rings.

![Problem 14.30
How many rings are present in each of the following compounds? Each consumes 2 mol of
hydrogen on catalytic hydrogenation.
(a) C₁0H₁8
(b) CgHg
(c) C8HgCl₂
(d) CH₂O
(e) C8H₁002
(f) C₂H₂CIO
(g) C3H5N
(h) C4H5N
Sample Solution (a) The molecular formula C₁0H₁8 contains four fewer hydrogens than the
alkane having the same number of carbon atoms (C₁0H22). Therefore, the index of hydrogen
deficiency of this compound is 2. Because it consumes two molar equivalents of hydrogen on
catalytic hydrogenation, it must have either a triple bond or two double bonds and no rings.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2c8c9d8-cb7d-4bb3-b241-ba372e4ba26e%2F16b4545c-f188-4265-95cb-50938f20b1b8%2F01iswx_processed.jpeg&w=3840&q=75)
