Question

Which carbon skeleton represents an ether?

(gradpoint)

Answer 1

Answer : The carbon skeleton represents an ether is
`C-C-C-O-C-C-C`

Explanation :

Ketone : It is a functional group in which the the
`-CO` group is directly attached to the two alkyl group of carbon.

The general formula of ketone is,
`R-CO-R'`

Ether : It is a functional group in which the the
`-O` group is directly attached to the two alkyl group of carbon.

The general formula of ether is,
`R-O-R'`

Aldehyde : It is a functional group in which the the
`-CO` group is directly attached to the terminal alkyl group of carbon.

The general formula of aldehyde is,
`R-CO`

In the given image,

Image 1 carbon skeleton represents a ketone.

Image 2 carbon skeleton represents an ether.

Image 3 carbon skeleton represents an aldehyde.

Hnece, the carbon skeleton represents an ether is
`C-C-C-O-C-C-C`

Answer 2

The present carbon skeleton in an ether is C-C-C-O-C-C-C because ethers conatins C-O-C as functional group
