Hello students in this question we are asked to find out whether these molecules are polar, non -polar or ionic.
00:18
So first one is we have to find out between oxygen and oxygen.
00:24
To find out whether they are polar, non -polar or ionic, we need to find out the difference in electronegativity.
00:32
Difference in electronegativity of both the elements.
00:38
So here in this case it is oxygen.
00:40
Oxygen electronegativity is 3 .4.
00:43
So both oxygen is there.
00:45
So 3 .4 minus 3 .4 which is equal to 0.
00:50
Thus we can see if the electronegativity difference is 0, this means it is non -polar.
01:02
Now the second one is c .a.
01:10
And chlorine.
01:13
Here calcium has electronegativity 1 and chlorine has electronegativity 3 .2.
01:22
If we find out the difference, difference will be equal to 3 .2 minus 1, which is equal to 2 .2...
