So in atoms, electro -negativity refers to its ability to attract electrons to itself in a bond.
00:07
And so, electronegativity typically decreases moving down a group or a column on our periodic table, and electronegativity increases moving across a period or row on our periodic table.
00:18
And so bond polarities occur when the electronegativities of two atoms in a bond differ, causing one end of the bond to be partially negatively charged and the other to be partially positively charged.
00:30
And so, looking at our first functional group.
00:34
What we can see is we have a dipole in the direction of oxygen, because oxygen is more electronegative than carbon in our ketone.
00:43
Next, we have the following functional group where we have an alcohol group.
00:49
So oxygen is more electronegative than carbon.
00:52
So we have a dipole in the direction of our oxygen...
