Question

Explain why the dipole moment of CO2 is zero although it contains electronegative oxygen atoms . plzzz answer the question

Answer 1

The dipole moment if the carbon dioxide (CO2) molecule is zero. In CO2 molecule the angle between O-C-O is 180° therefore when the oxygen atom attracts the electron pair towards itself then it becomes partially negative an carbon atom becomes partially positive. So carbon attracts the electron pair which the another oxygen have. Now this all the things equally happens with the oxygen atom on either side of the carbon atom. Therefore the dipole moment is zero as all the charges cancels out but because of this CO2 molecule attains a resonance(mesomeric) structure.

Answer 2

Hello friend

carbon dioxide has a linear geometry it has carbon at its centre and oxygen on its both sides since oxygen is more electronegative than carbon electron cloud is more pulled towards oxygen and both oxygen pull the electron cloud with the same tedency from both side therefore the net resultant becomes zero hence the dipole moment of co2 is zero.
