Theoretical bond angles

WebbExperimental measurements show that the actual bond angle is 104.5°. The difference between the predicted and observed bond angles can be explained by proposing, as we did for NH 3, that unshared pairs of electrons repel adjacent bonding pairs more strongly than the bonding pairs repel each other.

Webb1 feb. 2024 · The NCH approaches at a nearly perpendicular angle to the C1-Tr bond, between 91° and 99°. However, as the Tr atom grows larger there is an increasing tendency for the NCH molecule to pivot around its N atom, which decreases the θ (C-N⋅⋅⋅Tr) angle.

Webb1 maj 1986 · For C--C-C angles equal to 106 , 109.47 and 113 , the ot rotamer is preferred for C-C bond length values greater than 1.535, 1.515 and 1.475 A, respectively. An inversion occurs at the points mentioned, the O+ conformer being favoured in all three cases for shorter C-C bonds. WebbThere are two nuclei about the central atom, so the molecular shape is bent, or V shaped, with an H–O–H angle that is even less than the H–N–H angles in NH 3, as we would expect because of the presence of two lone pairs of electrons on the central atom rather than one. This molecular shape is essentially a tetrahedron with two missing vertices.

WebbThe theoretical study reported herein was performed using RI-BP86-D3/def2-TZVP [ 47, 48] level of theory. For the calculations, the X-ray coordinates were used by means of the program Turbomole 7.2 [ 49] since we are interested in evaluating the noncovalent contacts as they stand in the solid state.
