An alkene of molecular formula ${\mathrm{C}}_9{\mathrm{H}}_{18}$, on ozonolysis gives $2, 2-$dimethylpropanal & $2 -$butanone, then the alkene is

A substance ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$, yields on oxidation a compound, ${\mathrm{C}}_4{\mathrm{H}}_8\mathrm{O}$ which gives an oxime and a positive iodoform test. The original substance on treatment with concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$ gives ${\mathrm{C}}_4{\mathrm{H}}_8.$ The structure of the compound is

Here, $\mathrm{Z}$ is:
