Question

In the reaction : I2 + I- → I3-, the Lewis base is

Answer 1

Hi there,

Your answer is I-

# Explanation

Lewis Base: Lewis base is an electron donor species which can donate Electrons to another species.

I2 + I- ----> I3

In this specific reaction, I- can act as Lewis base. However, it can donate the pair of Electrons to some other species. This Electron donor species is called a Lewis base.

Hope it helps you.

Answer 2

The correct answer is I-

Lewis base is a particular species of electron donor species that donates electrons to the other species.

I2 + I- ----> I3

In the particular reaction given in the question, I- represents a Lewis base.  

Since there is a negative charge given in it, it is understood that it can act like an electron donor which will donate electrons to other species.
