As the title suggests, i am having difficulty understanding orbital hybridization, as well as pi and sigma bonds. Can someone help me out and/or point me in the right direction? Thanks

thomasxc said:so orbitals become hybridized because of electron repulsion?
nickdk said:All single (covalent) bonds are sigma bonds, and every bond after that is pi bonds. For example: If you have carbon bonded to four hydrogen atoms, then you have 4 single bonds, therefore you have 4 sigma bonds. Where as if you have elemental Nitrogen (N2), you have a triple bond, so there is 1 sigma bond in the triple bond, and the other two are pi bonds.
Single bond = 1 sigma bond
Double bond = 1 sigma bond + 1 pi bond
Triple bond = 1 sigma bond + 2 pi bonds
thomasxc said:that one helps a bit. and what about pi and sigma bonds?
thomasxc said:i understand this, (i think) but i am confused as to their orientation in reference to each other. my ap chem teacher made it seem like one surrounds/revolves around the other, but when i asked that specifically, he said no.
Orbital hybridization is a concept in chemistry that explains how atomic orbitals combine to form new hybrid orbitals in molecules. It is a model used to describe the shapes and energies of atomic orbitals in molecules.
Orbital hybridization is important because it helps us understand the bonding and structure of molecules. By knowing the hybridization of an atom, we can predict the geometry and properties of the molecule.
The type of hybridization in a molecule affects its bond angles, bond lengths, and bond strengths. This, in turn, influences the chemical and physical properties of the molecule, such as its reactivity and polarity.
The most common types of orbital hybridization are sp, sp2, and sp3, which involve the combination of s and p orbitals. Other hybridization types include sp3d, sp3d2, and sp3d3, which involve the combination of s, p, and d orbitals.
The hybridization of an atom can be determined by counting the number of electron groups (bonds or lone pairs) around the atom and using the following guidelines: sp for 2 electron groups, sp2 for 3 electron groups, sp3 for 4 electron groups, sp3d for 5 electron groups, sp3d2 for 6 electron groups, and sp3d3 for 7 electron groups.
