230424 The compound $\mathrm{X}\left(\mathrm{C}_3 \mathrm{H}_5\right)$ reacts with ammoniacal $\mathrm{AgNO}_3$ to give a white precipitate and reacts with excess of $\mathrm{KMnO}_4$ to give the acid, $\left(\mathrm{CH}_3\right)_2 \mathrm{CH}-\mathrm{COOH}$. Therefore, $\mathrm{X}$ is

1 $\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_3$
2 $\mathrm{CH}_3\left(\mathrm{CH}_2\right)_2 \mathrm{C} \equiv \mathrm{CH}$
