Electron arrangement for ClO2-

Postby Yinhan_Liu_1D » Sat Oct 29, 2016 12:05 pm

Is it similar to H2O? Since they are bothAX2E2.

Is the Electron arrangement for ClO2- trigonal pyramidal and the Shape angular?

I would really appreciate your help!

The bond angle is also less than 109.5, right?

I think you're correct on everything except that the electron configuration including the lone pairs is tetrahedral, not trigonal pyramidal, because their are four regions of electron density. Since two regions are lone pairs, we see the shape as bent instead of tetrahedral (just two of the branches of the tetrahedron). Tetrahedral bond angles are normally 109.5, but we'd expect it to be less than that for the bent shape because of the lone pairs.
