Example where we're going to be using our localized bond theory to explain the bonding between atoms in two different structures here.
00:09
So we've got hcn here, so we have a central carbon, and now carbon is in group four, and so it can singly bond to four other substituents.
00:23
However, in this case, three of those bonds are used up with a nitrogen molecule.
00:29
So we're still using up all four of carbons valence electrons.
00:35
And now our proton can only form a single bond.
00:38
And that is because hydrogen only has one electron.
00:44
Now our nitrogen has a lone pair because it is in group 5.
00:51
And so it will have a lone pair, as you can see here.
00:56
And then three of its electrons are occupied in the cn bond...
