Interpretation:
Among the given options, the characterization that is not compatible with triatomic molecule has to be chosen.
Concept Introduction:
Atoms of the element are the smallest particle that exists which has the properties of the element. If a group of atoms that is relatively small but bound together means it is known as molecule.
Molecules can be classified into various types. Diatomic molecule is a type of molecule that contains two atoms. The two atoms may be of same element or different element. Triatomic molecule is a type of molecule that contains three atoms. The three atoms may be from a same element or different element. This series goes on like this as tetraatomic, pentaatomic molecules etc.
If the molecules are to be classified on basis of observation then two types can be given. Homoatomic molecules are the ones that have the atoms of same kind in the molecule. Molecules that contains same type of atoms in it has to be an element. Heteroatomic molecule is the one that contains two or more kinds of atoms in a molecule.

C60H111O51 Use the following information to answer the following questions."The native structure of hemoglobin (HB) comprises of two α and two β subunits, each of which carries a heme group. There appear to be no previous studies that report the in-vitro folding and assembly of Hb from highly unfolded α and β globin in a 'one-pot' reaction. One difficulty that has to be overcome for studies of this kind is the tendency of Hb to aggregate during refolding. This work demonstrates that denaturation of Hb in 40% acetonitrile at pH 10.0 is reversible."
