Bond Problems
Carbon and Hydrogen
CH4
Define electronegativity?
the tendency of an atom to attract a shared pair of electrons in a chemical bond
What is the VSEPR theory?
a chemical model that predicts the 3D shape of molecules by assuming that electron pairs in the valence shell of a central atom repel each other and arrange themselves to minimize this repulsion
