Hello, students, today's question is about, so we have this compound.
00:05
So we have this compound available and we have to dissolve it in certain solvent and we have to find the following characteristics, following questions about this molecule.
00:15
So whether this molecule is hydropobic, hydrophilic and what kind of association it has with water or oil and it's a thermodynamic considerations and structures that make an association with water and interaction with water.
00:28
So basically we have to, first of all, we have to find out whether it is an, hydrophobic or hydrophilic.
00:34
So what is hydrophilic? hydrophilic means that water loving and hydrophobic is water hating.
00:42
So any compound they become water loving if they have more, if they have more polar groups.
00:50
They have more polar groups.
00:53
But if they have more non -polar groups, they become water hating.
00:59
So, let's take the look and examine this diagram.
01:04
So first of all, we can see that here we have oh.
01:07
So, oh is hydroxyl group.
01:09
So that is hydroxyl group, which is polar, which is actually polar.
01:14
So that is water loving.
01:16
But rest of the molecule, rest of the molecules, so of this chain, so they contain highly non -polar, highly non -polar substances.
01:25
So overall this chain become, overall this molecule become non -polial.
01:29
Polar molecule.
01:31
So, non -polar means that this becomes hydrophobic molecule.
01:36
Hydrophobic and this is a structure of vitamin a, vitamin a or retinoles or retinoic acid, but we see.
01:45
So it is a hydrophobic molecule because it has only one polar group, one polar group, but rest of the region contain the non -polar.
01:54
Rest of the region contain the non -polar.
01:57
So that is by whenever it associates with water...
