Consider the structure of ${\left({\mathrm{CH}}_3\mathrm{COOH}\right)}_2$ given below:

Select the correct option.

The bond length of $\mathrm{C}=\mathrm{O}$ is grater than the $\mathrm{C}-\mathrm{O}$ bond. Hence, x<y
The bond length of hydrogen bond showed by the dotted structure is less than the O-H bond. Hence, w<z
The bond angle for the single bond is less than the double bond. Hence, α<β
The bond length of $C-C{H}_3$ and $C{H}_{\mathit{3}}\mathit{-}C$ bond is the same. Because bond length for the same bond irrespective of the structure is the same. Hence, u=v
