Here we're going to take a look at making aloea structure for this compound.
00:10
And we're told it's a nitrosal azide.
00:15
So it's got four nitrogen, one oxygen.
00:17
Let's find, first of all, how many electrons we're dealing with.
00:20
So nitrogen's group five, i have four of them.
00:23
So that's 20 electrons from the nitrogens.
00:27
Oxygen's group six.
00:28
That's six more electrons.
00:30
So a total of 26 electrons.
00:32
Then that we need to account for.
00:34
We're told that the four nitrogen are bonded in order and the oxygen is at the end of the molecule.
00:42
So the first thing we're gonna do is just create single bonds between each of the bonding atoms.
00:48
And that uses up two, four, six, eight of the 26 electrons.
00:53
So we have 18 more to account for.
00:58
Let's just start making octets of electrons around the atoms that are.
01:03
At the end of the molecule first.
01:06
Okay.
01:08
And that just allowed us to use up 12 of the 18 electrons.
01:12
So we still have six left.
01:15
And we'll just kind of keep working our way inward here.
01:19
So on the remaining three atoms, we'll just put the remaining lone pairs of electrons.
01:27
And at this point, then, we have used up all of our electrons.
01:31
Now let's see who or what fulfills the architect.
01:35
So both of the outside atoms have an octet around them.
01:41
And the inner atoms, the three inner nitrogens, all have six electrons around them at this point.
01:57
I can see at this point that not everything has an octet of electrons around it.
02:02
In fact, really none of the interior atoms do.
02:06
And so we need to do some sharing of electrons to make that happen...
