Q. The carbon dioxide molecule is linear. The electronegativities of $C$ and $O$ are $2.5$ and $3.5$ respectively. Based on these values and on consideration of molecular geometry, the $C - O$ bond is...... and the molecule is......

Chemical Bonding and Molecular Structure

Solution:

Based on (electronegativity) difference $( C - O )$
bond is polar. But dipole moment of one $(C-O)$
side is compensated by that of other $(C-O)$ side
$\mu_{\text {Total }}=\vec{\mu}_1+\vec{\mu}_2$
$=\vec{\mu}_1+\vec{\mu}_2=0$
