Answer : The carbon skeleton represents an ether is [tex]C-C-C-O-C-C-C[/tex]
Explanation :
Ketone : It is a functional group in which the the [tex]-CO[/tex] group is directly attached to the two alkyl group of carbon.
The general formula of ketone is, [tex]R-CO-R'[/tex]
Ether : It is a functional group in which the the [tex]-O[/tex] group is directly attached to the two alkyl group of carbon.
The general formula of ether is, [tex]R-O-R'[/tex]
Aldehyde : It is a functional group in which the the [tex]-CO[/tex] group is directly attached to the terminal alkyl group of carbon.
The general formula of aldehyde is, [tex]R-CO[/tex]
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 [tex]C-C-C-O-C-C-C[/tex]
