Question

Assertion: In the solution of K in liquid `NH_(3)`, blue colour appears.
Reason: K reacts with `NH_(3)` to form `KNH_(2)`
A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are False

Answer 1

Correct Answer - B
`K+NH_(3)("liq")rarr[K^(+)(NH_(3))_(x)]+underset("ammoniate electron")underset("blue color due to")([(e^(-)CNH_(3))_(y)])`
`[K(NH_(3))_(x)]^(+)rarrKNH_(2)+H^(+)`
`H^(+) + e^(-) rarr H`
`H + H rarr H_(2)`
Both are correct
