Question

What is the bond angle in the ClO2- ion?

Answer 1

I believe.. it is bent( molecular geometry) with 109.5 bond angle because of the two lone pairs on Cl..So it would be tetrahedral for the electron geometry..

Answer 2

Why would it be 109.5? Why not 120? o.O

Answer 4

This worksheet helped me out with this.... http://ezquer.ro/?p=335

Answer 5

Thanks but all I see is <<109. Doesn't that mean less than 109? (Sorry, not really good at this)

Answer 6

No worries. Okay first, you draw the lewis dot structure....you then see how there is two lone pairs on the Cl..this shows that it's tetrahedral for the base geometry but since there's 2 lone pairs that alters the bond angles. ...and I could be wrong. But that sheet helped me through chem 101. I should of told you it was <<109.5 before.

Answer 7

It's very similar to water, except that there are \(\pi\)-bonds involved in stead of \(\sigma\)

Answer 8

oooooh ok. I was reviewing my material and came up with 104.5. Is that plausible?

Answer 9

Well, this is the structure:

Answer 10

unlike water, there are double bonds rather than single bonds. and double bonds are shorter.

Answer 11

That can't be the structure because it's not fulfilling the octet rule.

Answer 12

period 3 elements don't have to follow the octet rule.

Answer 13

I'm pretty sure they do follow the octet rule. (except Hydrogen)

Answer 14

I mean, you COULD draw it as a resonance structure if it makes you feel more comfortable :)

Answer 15

sorry it's crappy, but this is what it should look like
