Both the endo- and exo-bicyclo[2.1.0]pent-2-yl radicals are significantly pyramidal, but are nearly equal in energy (Delta E < 0.3 kcal/mol) and are separated by a very low (<0.4 kcal/mol) barrier. The barrier for trapping the bicyclopentyl radical by H2S is 1.5 kcal/mol lower for the endo radical.

N (SiH3)3 compouding is planar with an sp2 nitrogen, while the geometry of N (CH3)3 is pyramidal with an sp3 nitrogen. The planar geometry in N (SiH 3)3 is due to pp- dp bonding between a nitrogen 2p orbital and empty 3d orbitals on Si. This p-bonding decreases the Lewis basicity of N (SiH3)3 by delocalizing the nitrogen lone pair.

Solid-state structures of [M III (N″) 3] complexes are typified by either trigonal-planar (D 3h) or trigonal-pyramidal (C 3v) geometries, with all f-block examples exhibiting the latter shape. The pyramidalization of [Ln(N″) 3 ] has been rationalized by various arguments, including involvement of n d orbitals and dispersion effects (8b, 13) and dipole stabilization by deviation of the Ln(III) cation from the N 3 plane.
Draw Lewis structures and give the other information requested for the following: (a) SO3. Polar or nonpolar molecule? (b) PF3. Polar or nonpolar molecule? (c) F3SiH. Show the direction of the resultant dipole moment. (d) SiH3 2. Planar or pyramidal shape? (e) Br2CH2. Polar or nonpolar molecule?
