Lay hair from lie Versailles calm and in this video we'll continue our organic chemistry acid based discussion by looking at how the atom holding the acidic hydrogen will impact its acidity if you miss the earlier videos in this series you can find them alone with my acid based practice quiz and cheat sheet by visiting my website layer for sitcom slash acid base when learning about acid strength you tend to think of it in terms of the hydrogen atom falls off the hydrogen atom breaks off, but it's really about the atom holding that hydrogen atom and what happens to the atom when the hydrogen is gone when comparing acid molecules and looking at the atom holding the acidic hydrogen we're looking for two different trends when the atoms are in the same period you look at electronegativity and when the atoms are in the same group you look at the size for example let's say you're asked to rank the following molecules from low to high or an order of increasing acidity in the last video we set a look at the charge, so we draw it out and look at the acidic hydrogen and yes they all have the same charge they're all neutral, so you write out their acid-base reactions remove that acidic hydrogen and show the resulting conjugate base and once again they all have the same charge they're all negative one so how do you tell which is the stronger acid or rather how do you tell which is the more stable conjugate base this is where we have to take into account the periodic table trends in my intro to or agave series I told you that despite 100 plus atoms on the periodic table there are 10 that you have to memorize, and they're as follows hydrogen in period one period — we have C n o F period through we have phosphorus sulfur chlorine and then below that bromine and iodine there are two trends that I had you know with this the electronegativity increasing up and towards the right and size increasing down and towards the left if you haven't memorized that yet do so right now because acids and bases is one of the key topics where you must must must know these atoms when we're looking at atoms holding the acidic hydrogen, and they all happen to be in the same period remember period is going across then you have to look at their electronegativity if electronegativity is often towards the right that means as you go more towards the right on the periodic table the atoms get more and more electronegative the example above has a negative carbon nitrogen and oxygen but don't memorize the answer instead think of it this way what does it mean for an atom to be more electronegative it means of that atom wants negativity it wants electrons and that means if it really wants the electron then when it gets the electron it's going to be happy to have that electron so looking back at our example because oxygen is the most electronegative, and it wants the electrons most when it gets those electrons and gets a negative charge it's going to be the happiest it's going to be the most...
