The list gives the order of some metals and hydrogen in the reactivity series.
Metal $$X$$ is also included.
Most reactive $$K$$
$$Mg$$
$$Zn$$
$$H$$
$$X$$
least reactive $$Cu$$
Which of the following correctly shows the properties of metal $$X$$?
A
Reacts with dilute acids - no, oxide reduced by carbon - no
B
Reacts with dilute acids - no, oxide reduced by carbon - yes
C
Reacts with dilute acids - yes, oxide reduced by carbon - no
D
Reacts with dilute acids - yes, oxide reduced by carbon - yes
Correct option is B. Reacts with dilute acids - no, oxide reduced by carbon - yes
Solution:- (B) Reacts with dilute acids - no, oxide reduced by carbon - yesThe metals which are lying below hydrogen in the metal reactivity series cannot reacts with dilute acids as they are considered to be less reactive than hydrogen.
Carbon is above element $$X$$ in reactivity series, thus can easily reduced oxide of metal $$X$$.
