Experiment 9: VSEPR General Chemistry I and II Lab Manual Dakota State University Page 108 of 232 This looks quite different from our Lewis-Dot rendering. Each hydrogen is evenly distributed about the carbon in three dimensional space, with angles of about 110 o . In our Lewis-Dot structure, it looked as if the molecule would be square planar. This point cannot be stressed too strongly: Lewis-Dot structures give bonding information, but do not accurately represent the true shape of the molecule . Example 3: NOH This is a hypothetical molecule, that would be called "Nitrosyl Hydride", except that I cannot find reference to it anywhere so I doubt that it actually exists (it more than likely

Unformatted text preview: immediate breaks down to more stable compounds). We can make a Lewis-Dot structure for it, though, whether it exists or not. The fact that it does not implies that it would be highly unstable. None the less, let's imagine what it should look like, if, indeed, we could make it. The Lewis-Dot structure would look like this: So, let's go through it. Central element is nitrogen; there is one lone pair and two atoms giving a set number three. This gives us the trigonal planar parent structure, but the bent molecular shape. It would look as follows:...
