Determining Polydentate

Postby Alyssa Pelak 1J » Mon Nov 20, 2017 9:13 am

I am still a little confused on how we determine whether a ligand is polydentate or not. I understand what polydentate is, I am just unsure of how I would know whether it can bond more than one time?
Can someone please explain how you can determine this? For example in textbook problem 17.33.

You have to look at the molecule and see if it has any atoms that can serve as part of a Lewis base. To know if it's polydentate you need to kind of have the Lewis structure of the molecule in mind to see if there is more than 1 lone pair that can be bonded to the same central metal ion. I try to draw out the Lewis structure to kind of see if it allows for multiple bonding to the same metal ion. Hope this helps!
