Concept explainers
(i)
Interpretation:
The compound with the most polar bond has to be found.
Concept Introduction:
Polarity results from the uneven partial charge distribution between various atoms in a compound. Atoms, such as nitrogen, oxygen, and halogens that are more electronegative have a tendency to have partial negative charges. Atoms, such as carbon and hydrogen, have a tendency to be more neutral or have partial positive charges.
Polar nature of the molecules can be measured by the dipole moment. If a molecule has zero dipole moment then it is a non polar molecule. If a molecule has a net dipole moment then it is a polar molecule.
(ii)
Interpretation:
The non polar compounds has to be list
Concept Introduction:
Refer part (i).
