Give the common name for each of the following: a. CH 3 −CH 2 −O−CH 2 −CH 2 −CH 3

All right. Hi, everyone. So this question is asking us to provide the common name of CH three och two ch two ch two ch two ch three. Option A says methyl Buttal Ether. Option B says Ethel Beetle Ether. Option C does Methyl Pencil ether. And option D says Ethel Pencil. Et so let's go ahead and get started. The first thing I want to point out here is that in the structure provided we have one oxygen atom in between two carbon atoms or two ocho groups. Now this matches the general formula ror which is characteristic of an ether. So recall that the common name of an ether is generated by first listing the groups connected to oxygen in alphabetical order, followed by the word ether. So to the, to the left side of the oxygen atom is simply a one carbon chain or a CH three, which would correspond to a methyl group. And on the right side, if I go ahead and I count the number of carbons of the second all kill group, I can see that it is of in fact a five carbon chain. And so a five carbon chain treated as a substituent would be described as a pal group. So now these are the names that I would place in alphabetical order, followed by the name Ether. Now recall that if the ocho groups were identical, I would use the prefix dye to indicate that there are two of the same ocho group present. But in this case, that rule doesn't apply. Now because the M in methyl goes before the p in pal, the metal group is the first substituent I would list. So that's methyl por ether with spaces in between all three words. And so the common name of the compound provided is methyl pencil ether, which corresponds to option c the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found the South.

Textbook Question

Give the common name for each of the following:
a. CH₃−CH₂−O−CH₂−CH₂−CH₃

Verified step by step guidance

Step 1: Recognize the functional group present in the compound. The structure CH₃−CH₂−O−CH₂−CH₂−CH₃ contains an oxygen atom bonded to two alkyl groups, which identifies it as an ether.

Step 2: Recall the naming convention for ethers. In common naming, ethers are named by listing the names of the two alkyl groups attached to the oxygen atom in alphabetical order, followed by the word 'ether'.

Step 3: Identify the two alkyl groups in the compound. The group on the left of the oxygen atom is CH₃−CH₂− (ethyl group), and the group on the right is CH₂−CH₂−CH₃ (propyl group).

Step 4: Arrange the alkyl groups alphabetically. 'Ethyl' comes before 'propyl' alphabetically.

Step 5: Combine the names of the alkyl groups with the word 'ether' to form the common name. The common name of the compound is 'ethyl propyl ether'.

Key Concepts

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

Ether

An ether is a class of organic compounds characterized by an oxygen atom connected to two alkyl or aryl groups. In the given molecular structure, the presence of the -O- group between two carbon chains indicates that it is an ether. Ethers are commonly used as solvents and in the synthesis of various chemical compounds.

Alkyl Groups

Alkyl groups are derived from alkanes by removing one hydrogen atom, resulting in a group of carbon and hydrogen atoms that can attach to other molecules. In the provided structure, the two carbon chains (CH₃−CH₂− and CH₂−CH₂−CH₃) represent alkyl groups that flank the ether oxygen. Understanding alkyl groups is essential for naming and identifying organic compounds.

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming chemical compounds based on their structure and functional groups. For ethers, the naming convention typically involves identifying the alkyl groups attached to the oxygen and combining their names with 'ether.' In this case, the compound can be named as ethyl propyl ether, reflecting the two alkyl groups present.
