Bond Parameters

The least stable canonical structure among these is

${\text{C}\text{H}}_2=\text{CH}-\text{C}\text{H}=\text{C}\text{H}-{\text{CH}}_3$ is more stable than ${\text{CH}}_3-\text{CH}=\text{C}=\text{CH}-{\text{CH}}_3$ because

$\left(\text{I}\right){\text{CH}}_2=\text{CH}-\text{CH}={\text{CH}}_2$

$\left(\text{I}\text{I}\right){\stackrel{\ominus }{\text{C}}\text{H}}_2-\text{CH}=\text{CH}-\stackrel{\oplus }{\text{C}}{\text{H}}_2$

$\left(\text{I}\text{I}\text{I}\right){\stackrel{\oplus }{\text{C}}\text{H}}_2-\text{CH}=\text{CH}-\stackrel{\ominus }{\text{C}}{\text{H}}_2$
