7)How many molecules from the list below are polar?
Determine the covalency of the following and put them in decreasing order:
Br₂, SO₂, NH3, HCL
In the actual molecule of which this is a Lewis structure, which of the labeled distances can change?
marked
H-O
کا
unmarked
A
-H
H
List all the distances that can change. For example, suppose all the distances were measured at a certain time, and again 0.1s later. If distance A might be 50%
bigger or smaller the second time, but all the other distances are certain to be the same, you should write "A". If A and B might be different the second time,
but no other distances, you would write "A, B". And so on.
Note for advanced students: you can assume the molecule is dissolved in an appropriate solvent at room temperature.
0.0,...
You can click the "unmarked" tab to see the molecule without any of the distances marked.
