Welcome back, everyone is the given image a possible structure for C five H 02 Pavelic acid, if not described the changes that need to be done so that it becomes a more possible structure, we need to begin by calculating total valence electrons for Pavelic acid. So beginning with carbon recall that it is a group for a atom corresponding to four valence electrons. And because we have five atoms, we're going to multiply by five to give a contribution of 20 valence electrons from carbon. Now moving on to hydrogen recall that it's a group, one a atom on the periodic table corresponding to one valence electron and we have atoms of hydrogen. So multiplying by 10, this gives a contribution of 10 valence electrons from hydrogen. Now moving on to oxygen, we recall that it's a group six A Adam And this corresponds to £6 electrons which we multiplied by our two atoms of oxygen. So sorry, this is a two here And this is going to give a contribution of 12 vance electrons from oxygen. So adding up our total valence electrons, this will result in a total of 42 valence electrons total for Pavelic acid. Next, we should recall bonding preferences for our atoms. Recall that carbon has a bonding preference of four bonds. Recall that hydrogen prefers to have one bond and then recall that oxygen prefers to have two bonds with its two lone pairs on itself. So let's see if each of our atoms are bonded correctly. We can see that each carbon atom in the structure definitely does have four bonds, meaning that each of our carbons have formal charges of zero and are stable, whereas each hydrogen also only has one bond. So that means our hydrogen czar also stable with their single, directly attached valence electron being group one A atoms. And lastly, we can see that our two oxygen atoms in the structure have to bonds and two lone pairs on themselves. So our oxygen's are also stable with directly attached six valence electrons, keeping them with a formal charge of zero being group six A atoms. And so now we can count our total valence electrons to see if it matches with what we calculated for Pavelic acid. Recall that a bond represents two electrons. So we would count 2468, 10 12 14 16 18 2022 24 26 30 32 34. And then adding our lone pairs, we would have 35 36 37 38 39 41 42. So this matches up with our 42 valence electrons that we calculated because 42 valence electrons are used in our structure. We could have also calculated it by taking the fact that our structure has 15 single bonds, one double bond and four loan pairs. So I'm just using shorthand here and we can write out the calculation that we have, as we stated in one single bond will correlate to two electrons, One double bond correlates to four electrons and one lone pair correlates to two electrons. So in our calculation, we can write out 15 times two electrons making up each of our single bonds plus our four Or rather plus R two double bonds times are times the four electrons that make up the double bonds Plus our one lone pair times the two electrons making up that lone pair. And so in this calculation, we will come up with a total of 42 electrons total, which again also matches what we counted that are used in our structure of Pavelic acid. So we can confirm that for our final answer, the given structure is a possible structure for our formula of Pavelic acid. And this will correspond the choice a and the multiple choice as our final answer. So I hope that this made sense and let us know if you have any questions.
