Question

Assertion :In the reaction, $I_2+I^{-}\to I_3^{-1},I_2$ acts as Lewis base. Reason: In this reaction $I^{-}$ donates an electron pair for sharing with iodine

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is D Assertion is incorrect but Reason is correct

Lewis acid => an electron acceptor
Lewis base => an electron donor
In the given equation $I_3^{-}$is formed.

$I^{-}$ is donating its pair of electron to $I_2$ through coordinate bond.
So $I_2$ acts as lewis acid.
$I^{-}$ act as lewis base.
