Question

Assertion : Copper$(II)$ iodide is not known.
Reason : $C{u}^{2+}$ oxidises $I^{-}$ to $I_2$.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

$C{u}^{+2}$ is more stable than $C{u}^{+}$(due to high hydration enthalpy), in case of iodine, $C{u}^{+2}$ oxidizes $I^{-}$to $I_2$.Hence Copper(II) iodide is not known.
