Give the IUPAC names of the following compounds. (c) (CH 3 ) 2 C=CHCOOH (d)

Hello, everyone. Today, we have the following problem, give an appropriate systematic name for each of the structures shown below. So we'll start with our first structure and we notice that it is a carboxylic acid. So for a carboxylic acid, we have to make that the priority in this compound. And so we will number, starting from the carbon. That is the carboxylic acid, seeing that we have 123 and four carbons in our parent chain. And so we also have to include the alkene in our parent chain. So if we were to put this together as a parent chain, we would list the alkene first. So p we will list the carbon at the beine is on which is two and then we end with OIC acid. And we see that we also have a couple of subs substituents on carbons two and three, those are two methyl groups. So our total name would be 23 dimethyl for the two methyl groups followed by our parent chain, which is butte to a wick acid. Now, for our second structure, we have a cyclohexane but with a carboxylic acid attached to it, the carboxylic acid is still the parent chain, but it will be a little different. It will be a cyclohexane carboxylic acid. So it is written out entirely. And then we look at the substituent and we noticed that our mouth group is trans to our carboxylic acid in a sense that it is on a wedge and our carboxylic acid is on a dash. So our name for the second compound would be trans, when it comes to numbering, we set the car. So we a acid gets a one. And then our substituent needs to have the lowest number of the lowest number when carbon, when numbering our carbons. So we give them methyl A two. So our compound name is trans dash two dash metal. And then we list our parent chain which we said before was cyclohexane carboxylic acid. And with that, we have solved the problem overall, I hope was helped. And until next time.

Textbook Question

Give the IUPAC names of the following compounds.
(c) (CH₃)₂C=CHCOOH
(d)

Verified step by step guidance

Step 1: Identify the longest continuous carbon chain that includes the functional group (in this case, the carboxylic acid group, -COOH). The carboxylic acid group takes priority in numbering, so it will always be at position 1.

Step 2: For compound (c), the longest chain includes four carbons, with the carboxylic acid group at position 1. The chain also contains a double bond between carbons 2 and 3. This makes the parent chain a derivative of 'butenoic acid.'

Step 3: Identify and name any substituents attached to the main chain. In this case, there are two methyl groups attached to carbon 2. This makes the substituent name '2,2-dimethyl.'

Step 4: Combine the substituent name with the parent chain name. The double bond's position is indicated by the lowest possible number, which is 2. The full name becomes '2,2-dimethylbut-2-enoic acid.'

Step 5: For compound (d), follow the same process: identify the longest chain, locate the functional group, and name substituents. If no structure is provided for (d), clarify the compound's structure to proceed with naming.

Key Concepts

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

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming organic chemical compounds. It provides rules for naming based on the structure of the molecule, including the longest carbon chain, functional groups, and the position of substituents. Understanding these rules is essential for accurately identifying and communicating the identity of organic compounds.

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 compound, the carboxylic acid group (-COOH) is a key functional group that influences the compound's reactivity and properties. Recognizing functional groups is crucial for determining the IUPAC name and understanding the compound's behavior.

Alkenes and Alkyl Groups

Alkenes are hydrocarbons that contain at least one carbon-carbon double bond, which affects their reactivity and physical properties. In the compound (CH3)2C=CHCOOH, the presence of the double bond indicates it is an alkene. Additionally, recognizing alkyl groups, such as the isopropyl group in this case, is important for naming and understanding the structure of the compound.
