Valence Bond Theory

Science / Chemistry / Valence Bond Theory: A theory that explains the shapes of molecules in terms of overlaps between half-filled atomic orbitals, or half filled 'hybridized' orbitals (which are a mixture of atomic orbitals).

Triple Bond

Science / Chemistry / Triple Bond: A covalent bond that involves 3 bonding pairs. In the valence bond theory, one of the bonds in a triple bond is a sigma bond and the other two are pi bonds. For example, the central bond in acetylene MORE

Pi Bond

Science / Chemistry / Pi Bond: In the valence bond theory, a pi bond is a valence bond formed by side-by-side overlap of p orbitals on two bonded atoms. In most multiple bonds, the first bond is a sigma bond and all of the others a MORE

Valence Bond

Science / Chemistry / Valence Bond: In the valence bond theory, a valence bond is a chemical bond formed by overlap of half-filled atomic orbitals on two different atoms. MORE

Sigma Bond

Science / Chemistry / Sigma Bond: In the valence bond theory, a sigma bond is a valence bond that is symmetrical around the imaginary line between the bonded atoms. Most single bonds are sigma bonds. MORE
