JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Statement 1: Alkaline earth metals are not easy to produce by chemical reduction.

Statement 2: Their aqueous solutions can not be used for displacing one metal by another.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Alkaline earth metals are themselves strong reducing agents, so no common chemical reductant can reduce their compounds to the free metal; they must instead be obtained by electrolysis (Statement 1, true). It is also true that their aqueous solutions cannot be used to displace other metals, since the alkaline earth
