Question

In the reaction $I^{\oplus }+I_2\to I_3^{⊝}$, the lewis acid is:

• A. $I_2$
• B. $I^{\oplus }$
• C. $I_3^{⊝}$
• D. $I_3^{⊝}$ and $I_2$

Answer 1

The correct option is A $I_2$

Lewis acid a compound or ionic species which can accept an electron pair from a donor compound. In the reaction $I^{-}+I_2\to I_3^{⊝}$, lewis acid is $I_2$ which accepts the electron pair from $I^{-}$ lewis base.
