ClO − 2 has 7 + 6 + 6 + 1 = 20 total valence electrons to distribute. Share 16. OF2 is just like H2O except H replaced by F. So, the bond angle is 109.5 degree. The bond angle of Cl2O is larger than H2O because in case of Cl, P double bonds can be formed as they can expand their shells , double bonds cause more repulsions , and hence bond angle increases. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Lewis structure of a molecule is the structure that depicts the bonding between the atoms and lone pairs on the atoms involved in the molecule. How long will the footprints on the moon last?
