Metal M is a major constituent of steel. On reaction with dilute hydrochloric acid, M releases a gas G which burns with a pop sound along with the formation of a greenish coloured solution C.
(iii) Which of the following metals will displace metal 'M' from its solution ‘C’?

Solution
The correct option is A Aluminium
The arrangement of metals as per reactivity series is: K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Ag > Au.
Lead, gold and silver are less reactive than metal M i.e. iron therefore they will not displace it from its compound C.
While aluminium being more reactive than iron will displace it from its compound C i.e. iron chloride and will result in the formation of aluminium chloride.
Therefore, option 'a' i.e. aluminium is the correct.
