2cI e) (7) Ie is a molecular constant called the moment of inertia, which for a diatomic molecule is Ie = µre 2, and µ and r e are, in turn, the reduced mass, (see above) and the equilibrium bond length of the molecule AB. Note that re is the internuclear separation for which x = 0 in equations (1) and (4) (i.e., the bottom of the potential ... In order to understand hydrogen bonds, you must first understand the nature of a special type of covalent bond called the polar covalent bond. 1. In polar covalent bonds, the electrons are more strongly attracted to one of the two atoms, usually oxygen or nitrogen, than to the other atom. 2.
Practice: True or False 1. All molecular compounds are composed of atoms of two or more elements. 2. All compounds are molecules. 3. Molecular compounds are composed of two or more nonmetals. 4. Atoms in molecular compounds exchange electrons. 5. Molecular compounds have higher melting and boiling points than ionic compounds.
