What is each ether’s systematic name? 1. CH 3 OCH 2 CH 3 2. CH 3 CH 2 OCH 2 CH 3

Welcome back everyone. What are the Iupac names of the following ethers? And we're given two ethers. Let's throw their bond line structures. The first one has an ethyl group B oxygen. And then on the other side of oxygen, we also have a four numbered carbon chain. 123. Why? Let's recall that whenever we want to give I back names to ether, we have to find the longer chain and we clearly see that the longer chain consists of or carbon atoms. And that's Beane, right? So the parent will always be called as an L cane, choosing the longest continuous carbon chain. And that would be the same. Now, oxygen will act as a substituent. So whatever is left, including oxygen is actually our substituent and we call it an alcoy substituent. Now, the question is, what kind of an oxy substituent do we have? Well, since we have two carbon atoms, that'll be and adding oxy at the end that oxy substituent is bonded to carbon number one of the parent because we want to minimize the lo count of the substituent. So we have everything that we need. We can say that the name of the structure would be one oxy indicating that the toxic group is bonded to carbon. Number one off, be same well done. And moving on to the second structure, we once again have an ether, there is a three member chain on the left of oxygen, 123 oxygen. On the right, we have a three member chain. Once again, they have equal lens. So we can choose the right side to be our parent in the left side. That would be our substituent. What about the parent? Well, it's a three member chain. So that's propane since it is an L cane. And on the left side, our substi is an Alcoy substituent and that alcoy substi has we carbons. So we would call it a prop boxy substi prop and oxy, that Propox substituent is bonded to carbon one of the parent because we want to minimize the lo count. So we're going to say that the name is one prop boxy and roping. That's it. We have the required names. The first structure is one oxy butane and the second structure is one Propox propane. Thank you for watching.

Textbook Question

What is each ether’s systematic name?
1. CH₃OCH₂CH₃
2. CH₃CH₂OCH₂CH₃

Verified step by step guidance

Step 1: Identify the functional group in the given molecules. Both molecules contain an ether functional group, which is characterized by an oxygen atom bonded to two alkyl or aryl groups.

Step 2: For systematic naming of ethers, use the IUPAC nomenclature. The ether is named as an alkoxy group attached to the longest carbon chain. Identify the two alkyl groups attached to the oxygen atom.

Step 3: For the first molecule (CH₃OCH₂CH₃), the oxygen is bonded to a methyl group (CH₃) and an ethyl group (CH₂CH₃). The systematic name is derived by naming the smaller alkyl group as the alkoxy substituent (methoxy) and the larger alkyl group as the parent chain (ethane).

Step 4: For the second molecule (CH₃CH₂OCH₂CH₃), the oxygen is bonded to an ethyl group (CH₃CH₂) and another ethyl group (CH₂CH₃). Since both groups are identical, the systematic name is derived by naming the ether as diethyl ether.

Step 5: Ensure the names follow the IUPAC rules and double-check the structure to confirm the correct identification of the alkyl groups and their positions relative to the oxygen atom.

Key Concepts

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

Ethers

Ethers are a class of organic compounds characterized by an oxygen atom connected to two alkyl or aryl groups. They have the general formula R-O-R', where R and R' represent hydrocarbon chains. Ethers are known for their relatively low reactivity and are commonly used as solvents in organic reactions due to their ability to dissolve a wide range of substances.

Nomenclature of Ethers

The systematic naming of ethers follows the IUPAC conventions, where the longest carbon chain is identified as the parent hydrocarbon, and the ether group is indicated by the suffix 'ether.' The names of the two alkyl groups attached to the oxygen are listed in alphabetical order, followed by the word 'ether.' For example, in the compound CH3OCH2CH3, the systematic name is ethyl methyl ether.

Structural Representation

Understanding the structural representation of organic compounds is crucial for identifying their functional groups and determining their names. In the case of ethers, the structure typically shows an oxygen atom bonded to two carbon chains. Recognizing the connectivity of atoms in a molecular structure helps in accurately deriving the systematic name and understanding the compound's properties.
