Good day, the topic is about solubility.
00:03
Solubility is governed by like dissolves -dissolves -like rule which states that molecules with the same polarity dissolve in each other.
00:11
In this problem, we wish to find which of the following molecules in a given option is least soluble in water.
00:19
We note that water is polar and so molecules that are polar will readily dissolve in water.
00:28
More specifically, water contains hydrogen binding.
00:33
And some molecules that can hydrogen bond with water are readily soluble in water.
00:39
Hydrogen bonding is present when hydrogen is bonded to electronegative atom, such as nitrogen, oxygen, and fluorine.
00:52
Note that this type of configuration, that's just you have h -bounded to n -o - or f, is present for butanel, which is an aldehyde that contains c -ho and also in hydroxy which is basically your oh.
01:14
Thus, dihydroxy butanel and one hydroxy 2butanone will readily dissolve in water because of the process of hydrogen bonded to oxygen that makes it capable to hydrogen bond with water...
