Q.
VSEPR theory suggests that bond length and bond angle depend upon the presence or absence of lone pairs. If the bond angle of H−O−H in H2O is 105∘(approx.) , then the bond angle of F−O−F in F2O will be
In F2O,F is more electronegative which attracts the bond pair electrons away from central oxygen atom. Which decreases the repulsion between bond pair of electrons, hence bond angle decreases.
