Question

Which of the following compounds contain ionic bonds? Which contain covalent bonds? Which contain coordinate covalent bonds? (A compound may contain more than one type of bond.) a. BaCl₂

Accepted Answer

Welcome back, everyone. We need to identify the bond present in magnesium acetate tied for part one or rather from our options. Our first option is that there is an ionic bond. Our second option is that it's a Covalin bond. Our third option is that we have a coordinate Covalin bond. And we have to note that there can be more type of one bond present in a compound. Recall that for an ionic bond, we have a transfer of electrons between our atoms and recall that also for an ionic bond, it's typically characterized between a metal plus a nonmetal. Next, we have Covalin bonds in which two atoms Share one or more electrons and is typically characterized as a bond between two nonmetal atoms. Lastly, we have a coordinate Covalin bond in which we should recall involves shared electrons between the same atom or we can say a shared pair of electrons from the same atom. An example, we can think of for a coordinate co valent bond would be in the falling compound where we have nitrogen bonded to boron, where boron is surrounded by three fluorine atoms And our nitrogen is surrounded by three hydrogen atoms. In this compound note that nitrogen has a formal charge of plus one and note that boron has a formal charge of minus one. Recall that boron Being in group three A corresponds to three valence electrons. And we can see that it's valence electrons are attributed from the Covalin bonds that it has with flooring where we would see that the two or the bond between nitrogen and bromine, we're sorry, nitrogen and boron that I'm outlining here. The electrons making up this bond are contributed from nitrogen. Recall that nitrogen is located in group five A on our periodic table corresponding to five valence electrons. And so we can see that it has three valence electrons directly attached to itself in Covalin bonds with hydrogen. And then its last two valence electrons are being shared to form a co valent bond with boron. Now, technically, since this valence electron is only singly attached to nitrogen directly, it would have four directly attached valence electrons one less than I would prefer, which is why we have that plus one formal charge. But as we stated, this bond here represents a shared pair of electrons from the same atom being our nitrogen atom. And so this would be identified as a coordinate Kobe like bond. So now looking at our answer choices, we have to consider magnesium acetate tied mg sub two recall that magnesium on our periodic table is located in group to a corresponding to two valence electrons and corresponding to magnesium being a metallic atom based on its position. Next, recall that a 17 is located in group seven a on a periodic table corresponding to seven valence electrons and corresponding to its position being considered a non metal. So in this case, in our compound, we have a metal plus a nonmetal meaning that this compound should be described as an ionic compound because it will involve the transfer of electrons between our metal magnesium two plus sentence in group two A and R nonmetal minus one since it's in group seven A on our periodic table. And sorry, this says group seven A And this is why we see in our formula given in the prompt that our ion charges have crossed. And so our charge on Magnesium has now become a subscript next to contain. And then our charge for a 17 has now become an implied subscript of one next to magnesium. So the only correct answer choice to complete this example is going to be that magnesium astin tide is a an ionic bond and this is the only bond present in this compound. So this is going to be our final answer to complete this example. If you have any questions, please leave them down below. And I'll see everyone in the next practice video.
