Draw line-angle structures for the compounds (a) through (h). e. (CH 3 ) 3 CCOCHCH 2 f. CH 3 COCOOH

Hey everyone. Let's solve this problem. It reads convert the condensed formula to the line angle structures for the following organic compounds. Well we know that the line angle structures are just the skeletal structures of organic compounds. And the most important thing to remember is that carbon is king which applies to all of organic chemistry really. But what I mean by this in regards to the line angle structures is that carbon represents the corners, corners and the ends of the lines. And The other important thing to remember is that four bonds make a happy carbon. Right? So if you're always checking that your carbon has four bonds and you go into drawing these structures, remembering that you will definitely be set up for success. So let's remember these things and start diving into our compounds. So I'm just going to rewrite this. We have ch 33 ch three's attached to carbon carbon, hydrogen oxygen. Okay. Ch. 33 cc H. O. So I always read these left to right and just sort of start drawing it from there. So we have a CH3 which we know is an ending that is important to remember And we have three of them. So I know that those three are coming off of the same carbon. Okay so let's draw those 123 coming off of that same carbon. And moving on we have that bonded to another carbon. So I can draw my next carbon and that next carbon has an H. And an O. Hm. Well I know carbon is happy with four bonds right? But this next carbon is only written next to three atoms, three other atoms. So what does that mean? Well I know one of my atoms has to be double bonded. And also if you recall this ending Ch oh looks familiar, right? It is an alga hide ending. You might not have learned the functional group names yet but that will definitely be helpful when you move forward in organic chemistry. Being able to recognize that C. H. O. Ending, it will always be drawn the same and it's a C. Double bonded to an O. And an H. Okay, so just like johnny taught us that C. H. O. Is the ending that will always look like this. Alright, good job you guys, let's do the next one. We have ch. three C. O. C. H. Two C. O. H. Okay so let's just start left to right. I have my CH three which I know is an ending. So I'll just draw that ending there and it's bonded to that next carbon. And then I see that that carbon is bonded to. Oh and CH two. Okay, well 90% of the time, if not more C. O. is going to be a ketone which is just a carbon steel within the chain. Right? As johnny taught us, C. O. Is a carbonell group that's usually inside within the chain. It's not an ending. And ketone is the functional name group functional group name. Sorry. So we have our CH three, the next carbon will have that C double bond. Oh and CH two is going to be within our chain. Right? Because we know that that carbon can only have two hydrogen. So it must have two other bonds on either side. So that's our CH two. Now we're moving on to this C. 00. H. Another very popular important ending. And this is a carb oxalic acid. That's the functional name. Car box cilic. Is that one L. Or two? I think it's one carb oxalic acid and this is something you will definitely become familiar with. It. Has that double bond. Oh and then another O. H. Group at the end. So if this was a little confusing, you might be asking Joanne, how did you know that this carbon is double bonded to that? Oh And is not drawn like this CH three. See oh Ch two, Right. Ch three, C. O. C. H. Two and then have the rest of our structure. Right Well what do I know about the rules that I mentioned, carbon is happy with four bonds And if this were the structure this would have to be CH2. Right? Because if not this carbon only has two bonds attached to it and that is not. Okay, so that's how I know that the structure is written this way and not this way. Okay, so I just wanted to mention that in case you were wondering how I knew it was double bonded to that carbon instead of being the next atom in the chain. Alright, I hope this is helpful, and thanks for watching.

Textbook Question

Draw line-angle structures for the compounds (a) through (h).
e. (CH₃)₃CCOCHCH₂
f. CH₃COCOOH

Verified step by step guidance

Step 1: Understand the line-angle structure representation. In organic chemistry, line-angle structures are a simplified way to represent molecules. Each vertex or end of a line represents a carbon atom, and hydrogen atoms are usually not shown explicitly unless they are part of a functional group.

Step 2: For compound (c) CH3CH2COCN, identify the functional groups and connectivity. The compound contains an ethyl group (CH3CH2-), a carbonyl group (C=O), and a cyano group (-CN).

Step 3: Draw the line-angle structure for compound (c). Start with the ethyl group, which is represented by two connected lines. Then, connect the carbonyl group to the ethyl group, followed by the cyano group. Ensure the correct connectivity: CH3CH2-CO-CN.

Step 4: For compound (d) CH2CHCHO, identify the functional groups and connectivity. The compound contains an allyl group (CH2=CH-) and an aldehyde group (-CHO).

Step 5: Draw the line-angle structure for compound (d). Begin with the allyl group, represented by a double bond between two lines. Then, connect the aldehyde group to the allyl group. Ensure the correct connectivity: CH2=CH-CHO.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Line-Angle Structures

Line-angle structures, also known as skeletal formulas, are a simplified way to represent organic molecules. In these diagrams, lines represent chemical bonds, and vertices or line ends represent carbon atoms. Hydrogen atoms bonded to carbons are typically omitted for clarity, assuming each carbon forms enough bonds to satisfy its tetravalency.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In the given compounds, recognizing functional groups like nitriles (CN) and aldehydes (CHO) is crucial for drawing accurate line-angle structures, as they dictate the connectivity and geometry of the molecule.

Carbon Chain Identification

Identifying the carbon chain is essential for constructing line-angle structures. It involves recognizing the longest continuous chain of carbon atoms and any branches or substituents. For example, in CH3CH2COCN, the main chain is a three-carbon chain with a nitrile group, while CH2CHCHO features a three-carbon chain with an aldehyde group at the end.
