Sharing two electrons by two hydrogen atoms permits _
Each one to have a stable closed shell configuration
stable closed shell configuration of H:H analogous to
He
H:H have 2 electrons and 2 protons like
He
Amount of energy required to dissociate a hydrogen molecule H:H is its _
Bond dissociation Enthalpy
Main contributor to the strength of the covalent bond of H2 is the _ exerted on its two electrons
Increased Coulombic force
Each hydrogen atom feels _ rather than one in an isolated hydrogen atom (increased Coulombic)
Attractive force of two nuclei
With four valence electrons, carbon normally forms
Four covalent bonds
In addition to C-H bonds, most organic compounds contain covalent _ bonds
C-C
