Statement I: Alkali metals dissolve in liquid ammonia to give blue solutions.
Statement II: Alkali metals in liquid ammonia give solvated species of the type `[M(NH_(3))_(n)]^(o+)` (M = alkali metals).

A

Statement 1 is true, statement 2 is true, statement 2 si a correct explanation for statement 10

B

Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 10

C

Statement 1 is true, statement 2 is false

D

Statement 1 is false, statement 2 is true

Text Solution

Verified by Experts

The correct Answer is:
B
Alkali metals in ammonia gives blue colour due to ammoniated `e^(-)`
`M + (m+n) NH_(3) to [M(NH_(3))_(n)]^(+) underset("cause blue colour")([e^(-)(NH_(3))_(m)]^(-)]`
