2F.1

Postby Annie Ye » Sun Dec 01, 2019 10:38 pm

State the relative orientations of each of the following hybrid
orbitals: (a) sp3; (b) sp; (c) sp3d2; (d) sp2.

Consider the number of atomic and hybrid orbitals involved in each of these
When there are 2 atomic/hybrid orbitals and the hybridization of the central atom is sp, the electron arrangement is linear.
When there are 3 atomic/hybrid orbitals and the hybridization of the central atom is sp2, the e- arrangement is trigonal planar
Likewise, 4 atomic/hybrid orbitals + sp3 --> tetrahedral, 5 atomic/hybrid orbitals + sp3d --> trigonal bipyramidal, 6 atomic/hybrid orbitals + sp3d2 --> octahedral

For example, (a) sp3 will have orbitals oriented towards corners of a tetrahedron (109.5 degrees apart)

I like to think of it in terms of VSEPR - 2 bonds/electron pairs = linear, so sp hybridization; 3 bonds/EP = trigonal planar, so sp2 hybridization, and so forth. The hybridization level is equal to the number of bonds/EP.
