This question asks us to draw the lewis structure of each of the four -part series and indicate what type of ligand each molecule is going to be.
00:14
So first we'll start with part a, which is an ethylamine.
00:18
Now, lewis structure is a representation of the valent shell electrons in a molecule.
00:25
And so the way that we draw this and the way that i like to draw this is by starting just going left to right.
00:32
You start with the ch3.
00:35
So you're going to draw the c with the three hs around it and show those bonds.
00:44
Then we move to the ch2.
00:47
So again, we're going to draw the c and the h.
00:52
And then we're going to go to the nh2.
00:57
Now the nitrogen has a lone pair.
01:00
So you're going to show those.
01:02
What type of ligand it's going to be? we know what type of ligna molecule is going to be based on the number of lone pairs or where your molecule is electron rich.
01:14
And in this case, we only have one location, which is this nitrogen.
01:18
And so this ligand is going to be monodentate.
01:26
This next molecule, the trimethal bosphine.
01:31
Again, we're going to go left to right.
01:33
So we're going to start with the phosphorus.
01:37
So p.
01:38
And then we have three ch3 molecules.
01:41
So we're going to draw c .h.
01:48
H.
01:49
H...
