Accepted Answer

Hi, everyone. Welcome back. Here's our next problem. Determine if CH three dash CH 2-0 dash, ch two dash CH two dash BR is an organic or inorganic compound. Identify the type of formula provided molecular expanded or condensed structural. And our answer choices are a inorganic molecular formula. B organic expanded formula C inorganic condensed structural formula or D organic condensed structural formula. Let's recall the recall. An organic compound is one with carbon, carbon or carbon hydrogen bonds and it can have other types of atoms, oxygen, nitrogen, sulfur phosphorus halogens are all common in organic molecules. And so the oxygen and bromine in the compound we're given are not issues and we see we have multiple carbon, carbon and carbon hydrogen bonds here. So this is definitely an organic compound. So we can go ahead and eliminate choice A which has inorganic and choice C which has inorganic. And we're left with a choice between B and D. When we think about what type of formulas is, we recall that molecular formulas only tell us the types of atoms we have. So which atoms and how many of each atom? But this gives us some information about bonds, these dashes indicate bonds between atoms. So we don't have a molecular formula, which makes sense since neither B nor D has that as an option. So then we need to look at condensed structural formulas. So this provides some information about at bonds. So it indicates some bonds to basically tell you how the atoms are attached to each other, but some atoms are shown as groups. So not every bond in the molecule is shown. And that is indeed what we see here. We've got things like our CH three and CH two written as groups, no bonds shown. But then the lines indicate bonds between these different atoms. So we're shown how the atoms connect to each other but not every single bond is detailed. So that's what we have here. So our answer choice is going to be choice D organic with a contented structural formula. Our last type of formula is expanded formula which shows every bond. So that would have lines for all of the CH bonds that are not indicated here since it's just written as CH three or CH two. That's why choice B is incorrect since this is not an expanded formula. So once again, our given molecule here is choice D an organic compound indicated with a condensed structural formula. See you in the next video.
