    Constitutional isomers of C3H6O | Extended 2.0 – Dr K

    Previously I’ve posted a video on drawing aldehyde and ketone for C3H6O. Recently, there was a request to post a video drawing the remaining isomers for C3H6O and that brings us to this video, so, here are the two structures. One for aldehyde and one for ketone. We’re going to continue on to figure out the rest of the isomers. Before we begin to find all the other isomers, it’ll be helpful for us to know a little bit about this formula, as in how many rings or pi bonds it can have. That brings us to calculating IHD for this formula. IHD stands for index of hydrogen deficiency. Sometimes…

    Constitutional isomers of C2H4O2 | Carboxylic acid & Ester – Dr K

    Question is asking us to draw out all possible carboxylic acid and ester isomers for C2H4O2. Carboxylic acid has a carboxyl group which is COOH whereas ester has a carbonyl group attached to O and C like this. C double bond O, OC. The difference between carboxylic acid and ester is carboxylic acid has a H connected to an O, whereas ester has a C connected to an O. Let’s start with carboxylic acid. Since we only have two carbons, so, we’ll place them next to each other and then we’ll add in the carboxyl group and then we’ll fill in the remaining bonds on carbon with hydrogens. So, each…

    Constitutional isomers of C3H6O | Aldehyde & Ketone – Dr K

    We’re gonna draw out all possible aldehydes and ketones isomers for C3H6O in this video. Before we begin, how many isomers do you think we will get? Do stay tuned until the end to compare notes. Let’s begin. A quick recap on the functional groups. Aldehyde has a carbonyl functional group which is C double bond O and it is connected to a hydrogen. Note that this CHO group is always at the first carbon for aldehyde. Whereas for ketone, it has the same carbonyl group but it is sandwiched between two carbons, no hydrogens here. Let’s start with aldehyde. Since we have 3 carbons, let’s place them next to…

    Constitutional isomers of C5H10O2 | Carboxylic acid & Ester – Dr K

    We’re gonna draw out all possible carboxylic acid and ester isomers for C5H1002 in this video. Before we begin, how many isomers do you think we will get? In fact, there’s quite a few, so, do stay tuned until the very end of this video. Let’s get started. Carboxylic acid has a carboxyl functional group which is C double bond O connected to an OH. Note that this carboxyl group is always a carbon-1 for carboxylic acid. Ester on the other hand, it has a carbonyl group connected to an O and that O is connected to a C, so, the difference between carboxylic acid and ester is, in carboxylic…

    Constitutional isomers of C3H6O2 | Carboxylic acid & Ester – Dr K

    We’re gonna draw out all possible carboxylic acid and ester isomers for C3H6O2 in this video. Have you tried out on your own? Stay tuned until the end of this video to compare notes. Let’s begin. Quick recap. Carboxyl group has a C double bond O, OH group. Whereas ester has a C double bond O, OC group. The difference between carboxylic acid and ester is that carboxylic acid has an H connected next to an O whereas ester has a C connected next to that O. Let’s start with carboxylic acid. Let’s place 3 carbons straight in a row and then we’ll add in the carboxyl group, COOH at…

    Constitutional isomers of C5H10O | Aldehyde & Ketone – Dr K

    We’re gonna draw out all possible aldehyde and ketone isomers for C5H10O in this video. Have you tried out on your own? Well, stay tuned until the end of this video to compare notes. Let’s begin. Quick recap. Aldehyde has a carbonyl functional group which is C double bond O connected right next to a hydrogen. Note that this CHO group is always at the first carbon for aldehyde, whereas for ketone, it has the same carbonyl group but it’s next to two carbons so there’s no hydrogen connected right next to the carbonyl group. That’s the difference between aldehyde ane ketone. Let’s start with aldehyde. Since we have five…

    Constitutional isomers of C4H10 | Alkanes – Dr K

    The question is asking to draw out all constitutional isomers for C4H10. Since this chemical formula fits in the general formula of CnH2n+2, that means it’s an alkane. Let’s start by drawing a four carbon chain, four carbons connected straight in a row like this. We know that carbon can make four bonds, and since the first carbon is already connected to one carbon, that means it, will connect to three hydrogens. The second carbon is already connected to two carbons on the left and right so that means it has a remaining of four minus two equals two bonds. The third carbon is the same as the second carbon,…

    Constitutional isomers of C2H4O | Aldehyde & Ketone – Dr K

    The question is asking us to draw out all possible aldehyde and ketones isomers for C2H4O. Aldehyde has a carbonyl functional group which is C=O connected to a hydrogen. Note that the carbonyl group in aldehyde is always at the first carbon, whereas for ketone, it also has a carbonyl group but it is sandwiched between two carbons, so, the difference between aldehyde and ketone is that they both have carbonyl group but in aldehyde there’s a H connected next to it. In ketone, both sides are carbon. So, let’s start with aldehyde. Since we only have two carbons, let’s place them next to each other and then we’ll add…

    Constitutional isomers of C4H8O | Aldehyde & Ketone – Dr K

    We’re gonna draw out all possible aldehyde and ketone isomers for C4H8O in this video. How many isomers do you think we will get? Well, stay tuned until the end of this video to find out. Let’s begin. Quick recap, aldehyde has a carbonyl functional group which is C double bond O connected to a hydrogen. Note that this CHO group is always at the first carbon for aldehyde. Whereas, ketone, it has the same carbonyl group but instead of hydrogen next to it, it’s sandwiched between two carbons. Let’s start with aldehyde. Since we have four carbons, let’s start by placing all of them in a straight line and…
