Concept explainers
(a)
Interpretation:
Polar molecules and the direction of its dipole moment have to be identified.
Concept introduction:
Polar Molecules:
Polar Molecules contains partial positive and partial negative charge in the molecule due its electronegativity difference between the molecules.
Dipole moment:
The charge separation of the molecule produces dipole moment. Dipole moment arises between two ions in an ionic bond or covalent bond.
Dipole moment depends on the differences in electronegativity of the atom in the molecule. The electronegativity is more, the larger the dipole moment. The dipole moment is calculated from the polarity of the molecule.
