WebThe index of hydrogen deficiency is a count of h ow many molecules of H 2 need to be added to a structure in order to obtain the corresponding saturated, acyclic species. Hence, the IHD takes a count of how many rings and multiple bonds are present in the structure, so the IHD can also be thought of as (multiple bonds + rings) or. IHD = π + r. Webchemistry Technetium-99m is a metastable nuclide used in numerous cancer diagnostic and treatment programs. It is prepared just before use because it decays rapidly through y emission: $^{99m} \mathrm { Tc } \longrightarrow ^ { 99 } \mathrm { Tc } + \gamma$ Use the data below to determine (a) the half-life of 99mTC; (b) the percentage of the ...
