Hello students, so in this video we are going to talk about the resonance structure of nitrate ion.
00:10
So, the structure of nitrate ion goes something like this.
00:13
So, n double bond o, o and o.
00:17
So, n has a total of 4 here valence electron and this oxygen has 2 lone pairs, this oxygen has 6 lone pairs and this oxygen also has 6 lone pairs.
00:31
So, it has a minus charge, it has a minus charge and nitrogen has a plus charge.
00:36
So, the resonance structure forms something like this.
00:39
So, this goes here and this comes here.
00:43
So, n will form a double bond here and it will have 2 electrons because, 2 lone pairs because it is given 1 lone pair to form the bond and this bond has opened up.
00:53
So, it has 6 lone pairs and a minus sign.
00:57
It has a plus sign and again this is the same.
01:00
Now, again what will happen is, this negative sign will go here and this will open up.
01:10
So, it will form something like this.
01:15
So, these are the 3 resonance structures for nitrate ions.
01:26
Now, we have 2 statements and we have to say whether they are true or not.
01:31
So, the first statement is the 3 resonance structures contribute equally to the structure...
