V S E P R 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 H 2 O is 105 ° ( a p p r o x. ) , then the bond angle of F - O - F in F 2 O will be
Options
- Agreater than 105 °
- Blesser than 105 °
- Cequal to 105 °
- Dequal to 180 °
Correct answer
B. lesser than 105 °
Step-by-step solution
In F 2 O , 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.
