Good day.

In this question, we are told that carbon tetrachloride was an active chemical ingredient used in fire extinguishers to extinguish electrical fires.
00:10
However, it is no longer in use because of the formation of a toxic gas foscine.
00:15
That was released when in use.
00:17
So in this question, we are going to write down the lowest structures for carbon tetrachloride and for fosgene.
00:29
And first gene is cl2 co.
00:35
So to begin with, we need to calculate the total number of valence electrons.
00:40
So the number of valence electrons for carbon are four plus for chlorine, it is seven times the total number of chlorine atoms in that compound, which is four.
00:56
And that gives us a total of 32 valence electrons.
01:01
Then the next step is to write down the least electronegative atom in the center, and then the surrounding atoms, which are chlorine, chlorine atoms...
