In the previous post, we talked about the hybridization of atomic orbitals, so this practice set is to master to concepts of determining whether an atom is sp, sp2, sp3, sp3d, or sp3d2 hybridized.
Practice
1.
a)Determine the hybridization, the electron- and molecular geometry of the following molecules.
| (a) BF3 | (b) CH2O | (c) HCN | (d) BeCl2 | (e) CH2Cl2 |
| (f) SOCl2 | (g) SO2 | (h) PCl5 | (i) XeO4 | (j) NCl3 |
| (k) SiCl4 | (l) SF2 | (m) H2S | (n) SO3 | (o) COCl2 |
| (p) PCl3 | (q) OF2 | (r) BrF5 | (s) N2O | (t) SF6 |
| (u) POCl3 | (x) XeF2 | (y) XeF4 | (z) C2H2 |
