Question

So2 can react with OH-1, forming HSo31. In this reaction, O the SO2 acts as a Brønsted acid, accepting a proton from the OH ion. O 2 the S02 acts as a Lewis acid, accepting a proton from the OH-1 ion. the OH1 ion acts as a Bronsted base, donating a proton to the SO2 o 3 molecule. 3) the OH ion is the Lewis base which donates an electron pair to the O 4) Lewis acid, SO2 to form a coordinate covalent bond. O s) the OH ion acts as a Lewis acid, accepting an electron pair from the So2 molecule to form a coordinate covalent bond.

Explanation / Answer

answer: both Lewis and Bronsted has a different definition of acid and base

according to

Lewis: electron donor is Lewis base and the electron acceptor is Lewis acid

Bronsted: proton(H+) acceptor is Bronsted base and proton (H+) donor is Bronsted acid

OH- is electron rich and SO2 is electron deficient because its attached to two oxygen atom with the double bonds and due to the more electronegativity of oxygen it makes sulfur partial positive and due to this sulfur can accept an electron

so the correct statement is 4)

the OH- ion is the Lewis base which donates an electron pair to the Lewis acid, SO2, to form a coordinate covalent bond
