When a metal X is treatwd with cold water it gives a basic salt Y with molecular formula XOH (molecular mass=40) and liberates a gas Z. Identify X, Y and Z and also write the reactions involved

Q. When a metal X is treated with cold water, it gives a base Y with molecular formula XOH (Molecular mass = 40) and liberates a gas Z, which easily catches fire. Identify X, Y and Z and also write the reaction involved.

Q. When a metal $X$ is treated with cold water, it gives a basic salt $Y$ with molecular formula $XOH$ (molecular mass $=40$) and liberates a gas $Z$ which easily catches fire. Identify $X,Y$ and $Z$.

Question 42
When a metal X is treated with cold water, it gives a base Y with molecular formula XOH (Molecular mass = 40) and liberates a gas Z, which easily catches fire. Identify X, Y and Z and also write the reaction involved.

Q. A compound $\left(X\right)$ with a molecular formula $C_5{H}_{10}O$ gives a positive 2,4-DNP test but a negative Tollen's test. On oxidation it gives a carboxylic acid $\left(Y\right)$ with a molecular formula $C_3{H}_6{O}_2$. Potassium salt of $\left(Y\right)$ undergoes Kolbe's reaction and gives a hydrocarbon $\left(Z\right)$ Identify $\left(X\right).\left(Y\right)$ and $\left(Z\right)$.

Q. A divalent metal with atomic number $12$ reacts with an acid liberating a gas $X$. $X$ on treatment with a non metal $Y$ gives $Z$, which on dissolution in water produces the same acid. Identify $X,Y$ and $Z$.
