Okay, which compound contains an atom with expanded octalate room? so first, let's look at them.
00:10
The first one, h -c -l -o.
00:13
So the center atom is chlorine.
00:16
If we try to draw the lewd structure, you'll find the chlorine has seven electrons.
00:23
So it tends to form a double bond with oxygen, and then a single bond with hydrogen.
00:30
So chlorine itself has seven valentons.
00:33
Electron now it used one to three three electrons so there would be another four electrons to form two long pairs so as you can see here it has one two three four five six seven eight nine ten electrons in the valence chair so the hc a cell has the expanded oscillate structure and the second one is h n o three so first, show the louis structure.
01:15
So in this case, it forms a double bond with auction, another double bond with oxygen, and oh bond.
01:24
So looking at here, you'll find nitrogen has already 1, 2, 3, 4, 5, 5 electron used.
01:33
And also, the surrounding electrons is 1, 2, 3, 4, 5, 6, 7, 8, 910.
01:41
10 valence electrons.
01:43
So it's also an expanded octalate.
01:52
And then you have the i3 minors.
01:55
So the structure looks like this.
02:04
So for the middle iron, it has seven base electrons...
