what is a bond in VB theory
localised bonds between a pair of atoms
define hybridization
atoms in molecules are able change the energies and shapes of their orbitals in order to bond with other atoms
what is sp3 hybridization
the 2s orbitals interacts with the three 2p orbitals to form four sp3 orbitals
where is the node in a sp3 hybridization
the nucleus
what does a sp3 hybridized orbital look like
an hourglass with one really big side
what atom uses sp3 hybrdization
carbon
why is methane tetrahedral
the carbon atom is sp3 hybridized meaning the repulsion of repulsion causes a tetrahedral
why is ammonia tetrahedral
it is sp3 hybridized so the lone pair doesn’t cause extra repulsion
what is sp2 hybridization
2s interacts with 2px and 2py to three sp2 orbitals
what molecule is an example of sp2 hybridization
ethene
what bonds make the double bond of ethene
a pi bond od pz and a sigma bond made of the hybridized sp2 orbitals
what molecule uses sp hybridization
alkyne
what is sp hybridization
2s and 2pz orbitals interact to form 2 sp hybridized orbitals
what orientation are the hybridized sp orbitals from each other
180 degrees with the large part of the hourglass pointing away
what types of bond is a triple carbon carbon bond made out of
linear sigma bonded framework using the hybridized orbitals
2px and 2py form two pi bonds at 90 degrees from each other
