Question
Can a non-polar molecule have polar covalent bonds? Explain.
Solution
Yes, it is possible in case of the linear molecule. For example, carbon dioxide is non-polar although both carbon-oxygen bonds in carbon dioxide are polar. Also, symmetrical molecules such as methane and carbon tetrachloride are non-polar although four carbon-chlorine bonds in CCl4 are polar because polarities of the bonds mutually cancel out and molecules are of non-polar nature.
