Solution
The correct option is DC4H6 In chain isomerism, or skeletal isomerism, components of the skeleton are distinctly re-ordered to create different structures.
Butane C4H10, Butene C4H8 and Butanal C4H8O shows chain isomerism but 1,3-Butadiene C4H6 can not be re-ordered to create chain isomer.
