1 / 1 ptsQuestion 27The sphybridization has what percent s character and what percent p character respectively?350%, 50% 25%, 75%
There are 4 orbitals being hybridized, 1 s orbital and 3 p orbitals. What percentage of the orbitals beinghybridized are 's' and what percentage are 'p?'
1 / 1 ptsQuestion 28What hybridization would you expect for Se when it is found in SeO?
3There are four areas of electron density around Se, giving it a tetrahedral electronic geometry. Thiscorresponds to sphybridization.
1 / 1 ptsQuestion 29Give the hybridization of each central atom in order from A to E:
sp, sp, sp, sp, sp233Hybridization is based on the electronic geometry around the central atom, which is based on thenumber of regions of high electron density (RHED) around the central atom. The RHED from A to E are3, 2, 2, 4, 4; giving electronic geometries of trigonal planar, linear, linear, tetrahedral, and tetrahedral;giving hybridizations of sp, sp, sp, sp, sp233sp, sp, sp, sp, sp32233sp, sp, sp, sp, sp222sp, sp, sp, sp, sp3331 / 1 ptsQuestion 30What hybridization would you expect for C in ethyne (CH )?22sp3sp Ethyne is a linear molecule with two central atoms each with 2 areas of electron density. It has sp hybridization.sp2sp d3
