: A bond pair is a pair of electrons present in a chemical bond. This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push away from) each other in three dimensional space and this gives the molecules their shape. {/eq} hybridized. stronger than that of normal orbitals. C4H8.
