What is a coordinate covalent bond, and how does it differ from a covalent bond?

Accepted Answer

Welcome back everyone. We have a true or false example. A coordinate Covalin bond is another term for a Covalin bond wherein two atoms share one or more electron pairs. We're going to begin by recalling that for a Covalin bond, we have the definition where to atoms Will share one or more electrons. And recall our definition for a coordinate Corby and Lynn bond in which a shared pair of electrons are coming from the same atom. Let's think of our compound NH three dot BF three which is ammonia triborough flooring, drawing out its structure, we have nitrogen surrounded by three hydrogen atoms And nitrogen is bonded to Boron which is bonded to three flooring atoms. Recall that boron is located in group three, a corresponding to three valence electrons and nitrogen is located in group five a corresponding to five valence electrons. Noticed that in the structure, we have a plus one charge on nitrogen and a minus one charge on boron. Now, this is due to the fact that boron, as we stated with its three valence electrons currently has directly attached four valence electrons, which is one more than I would prefer to have. And So that gives us its formal charge of negative one. Whereas nitrogen has directly attached four valence electrons, which is one less than I would prefer to have giving its formal charge of plus one. And noticed that as we stated, Braun only has three valence electrons being that it's from group three a. So that means that from the central bond here, these two electrons are going to be coming from nitrogen fully. So technically, we can say that nitrogen has its five valence electrons in the structure. However, two of its five valence electrons are being used to form a coordinate co violent bond to bromine. And so here we can see that nitrogen or we can say specifically in the nitrogen boron bond, the electrons our shared and come from nitrogen only. And so this is an example of a coordinate Covalin bond, meaning that we would determine that are given statement is a false statement. And our final answer is going to be that a coordinate Covalin bond is not another term for a Covalin bond where in two atoms share one or more electrons. This statement is true as stated but written the way that it is in the prompt, we would consider the statement false since the the terms are not interchangeable. So our final answer false corresponds to choice being the multiple choice. I hope this made sense. And let us know if you have any questions
