What Do You Think?. Provide the Lewis structure for CH 4 . Give the orbital notation for a carbon atom . Describe the inconsistency that exists between the number of bonds that carbon forms and its electron arrangement. Hybridization.
How does carbon form four equivalent, tetrahedrally arranged, covalent bonds?
This usually occurs only with the central atom in a molecule of polyatomic ion.
The four (s + p + p + p) hybrid orbitals in the sp3-hybridized methane molecule are equivalent: they all have the same energy, which is greater than that of the 2s orbital but less than that of the 2p orbitals.
The number of electron pairs on the central atom will determine the type of hybridization.
The second and third bonds of a multiple bond involve unhybridized p-orbitals.
The number of electron pairs contained by the central atom will determine the type of hybridization that occurs.
