Interpretation- To explain the polarity of
Concept Introduction- Polarity is defined through the difference in electronegativity of elements.
If the bonded elements have electronegativity difference, the bond is said to be polar otherwise it is nonpolar.
The molecule is said to be non-polar if the net dipole moment of the molecule is zero.
Explanation of Solution
The alkane molecules contain single carbon-carbon and carbon-hydrogen bonds. The carbon-carbon bonds are nonpolar as there is no electronegativity difference while the electronegativity difference for the carbon-hydrogen bond is negligible. Hence, the bonds are nearly nonpolar.
Since all the bonds have the same polarity and dipole moment each bond cancels out resulting in zero net dipole moment. Therefore, the alkanes molecules are nonpolar.
