Webb2 feb. 2024 · We have an angle of 26.87° for CLC-O and 22.10° for CLC-P, both formed between the aromatic rings of the two molecules, with a difference of 4.47° between the two regions, which is caused by this substitution. 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. WebbFor example, the calculated values of the bond angles differ from the corresponding experimental values by around 0.09°–3.5° for BP86 and around 0.48°–7.7° for B3lyp.
