Chemical Bond – a force causing a group of atoms to
behave as a unit; lower-energy state of the system
Example – for ethane (C2H6) we envision
one C-C bond and six C-H bonds
A bond can also be thought of as a
quantity of energy. The sum of
energies in the individual bonds is
equal to the energy of stabilization
for the entire molecule.
Covalent, polar covalent, and ionic
bonds are defined by the relative
electronegativities of the atoms
3
•All bonds of a particular type – eg, all C-H single bonds – have the same
amount of energy – simplifying assumption to understand molecular structure
•Energies for formation of a molecule from constituent atoms, and for
chemical reactions, can be calculated from this and similar tables.
•Breaking bonds costs energy, while forming bonds liberates energy
•Multiple bonds carry higher energies 4
Bond lengths for higher-energy multiple bonds are shorter
