Question

Match Column1 with Column 2

$\begin{array}{cc}\text{Column 1}& \text{Column 2}\\ \text{(i) Sodium}& \left(1\right)\text{Do not react stream}\\ \text{(ii) Aluminium}& \left(2\right)\text{Replace hydrgen}\\ & \text{from steam when red}\\ & \text{hot}\&\text{form respective}\\ & \text{oxides}\\ \text{(iii) Iron}& \left(3\right)\text{Replace hydrogen}\\ & \text{from steam only when}\\ & \text{metals are heated}\\ \text{(iv) Silver}& \left(4\right)\text{Replace hydrogen}\\ & \text{from cold water and}\\ & \text{produce their respective}\\ & \text{hydroxides}\end{array}$

• A. (i)-(4),(ii)-(3),(iii)-(4),(iv)-(1)
• B. (i)-(1), (ii)-(2),(iii)-(3),(iv)-(4)
• C. (i)-(2), (ii)- (3), (iii)-(1), (iv)-(4)
• D. (i)-(1), (ii)-(4),(iii)-(2),(iv)-(3)

Answer 1

The correct option is A

(i)-(4),(ii)-(3),(iii)-(4),(iv)-(1)

By experimental determination of rate of reaction with metals with water ,it has been possible to arrange the metals in serial order of decreasing reactivity is called as metal reactivity series. The above are the action of water with metals which show reactivity according to the reactivity series.
