Skeletal Isomers

Skeletal isomers are constitutional isomers that have the same functional groups but differ from each other in the connectivity of the carbon skeleton.

eg:  Butyl alcohol (1) and isobutyl alcohol (2) are constitutional isomers containing the same functional groups, namely the alcohol group.



They differ from each other in the connectivity of the carbon skeleton.



Thus, 1 and 2 are skeletal isomers.
