Question

how CO2 is a Lewis acid

Answer 1

hiii mate


hope this helps you

There are molecular compounds (such as carbon dioxide and sulfur dioxide) that are able to neutralize basic oxides and hydroxides. These neutralization reactions can not be described using either the Arrhenius or Brønsted theories since they do not involve protons. The chemical equation for the reaction of carbon dioxide neutralizing the strong base calcium oxide is shown below:

CaO(s) + CO2(g) –>CaCO3(s)

The Lewis Theory provides the best description for reactions such this. Carbon dioxide is a polar molecule whose positive center is on the carbon atom:


This positive center is able to attract (and accept) the lone electron pairs present on the oxide ion (O2-). Thus, carbon dioxide is acting as a Lewis acid and the oxide ion is acting as a Lewis base.

Answer 2

HI HERE IS THE ANSWER
CO2 IS A POLAR MOLECULE WHOSE POSITIVE CENTER IS ON THE CARBON ATOM . THIS POSITIVE CENTER IS ABLE TO ATTRACT AND ACCEPT THE LONE ELECTRON PAIRS PRESENT ON THE OXIDE ION (O²-). THUS CARBON DIOXIDE IS ACTING AS A LEWIS ACID.
