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. 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.
