Our tutors rated the difficulty of Compare the bond angle in H2O to OF2. Do they dipole or not? The oxygen atom in OF2 undergoes sp3 hybridization, much like the oxygen atom in water. Because the lone pair of electrons occupies more space than the bonding pairs, we expect a decrease in the Cl–Sn–Cl bond angle due to increased LP–BP repulsions. OF2 gemometry: sp3 hybridized atoms adopt a tetrahedral geometry. The lone pairs exert force on the bonded pair electrons and bonds shift towards downward resulting in the V-shaped molecule OF2. This small difference is due to the electronegativity of the atoms involved in the substances. Still have questions? I agree in college students should know to subtract 2.5 degree for each lone pair.
