The Octet Rule in Covalent Bonding Triple Covalent Bond: a bond formed by sharing three pairs of electrons Copyright © Pearson Education, Inc., or its affiliates. All Rights Reserved.

Bond Dissociation Energies Bond Dissociation Energy: energy required to break the bond between two covalently bonded atoms. Bond Bond Dissociation Energy (kJ/mol) Bond Length (pm) C C 347 154 C = C 657 133 908 121 Copyright © Pearson Education, Inc., or its affiliates. All Rights Reserved.

The Octet Rule in Covalent Bonding Drawing Lewis Dot Structures: Determine # of valence electrons. Determine # of “octet” electrons. *Note*– Hydrogen gets 2 # bonds = (# valence e- - # octet e-) / 2 Arrange atoms with # bonds from step 3. Add electron pairs until all atoms have the correct number of electrons around them Recheck your answer to make sure you have the right # of bonds and electrons.
