Okay, determine whether each molecule in exercise 36 is polar or non -polar.
00:13
So whether the molecule is polar or non -polar will look at the dipole moment.
00:19
To look at whether the molecule has its dipole moment.
00:23
What is the dipole moment? it's actually the separation of the centers of the charge.
00:37
Basically, there's a separation between the positive charge and the negative charge.
00:42
So we will know, in some of the particles.
00:44
Case, right, when we draw a molecule, some of the atoms tends to carry negative charge.
00:56
Some atoms tend to carry positive charge.
01:02
So when we look at those molecules first, we determine which one tends to carry negative charge, which one tends to carry positive charge.
01:12
For example, like water, we know oxygen tends to be negative, right? hydrogen tends to carry positive.
01:20
Charge.
01:22
So this is the first step.
01:24
The second step is to draw the geometry of that molecule...
