g All of the molecules below have polar bonds but only one of the molecules is a polar molecule. Which one is a polar molecule?
A) C2F2 B) C2Cl4 C) CO2 D) NF3 E) CF4
1 answer:
Answer:
Explanation:
Geometrical symmetry of the molecule and the polarity of the bonds determine the polarity of the molecule.
The molecule that has zero dipole moment that means it is a geometrically symmetric molecule and the molecule which has some net dipole moment means it is a geometrically asymmetric molecule.
As the molecule is symmetric, the dipole moment will be zero as dipole moments cancel each other and the molecule will be non-polar.
As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.
Example:
Thus, we can say that is a polar molecule.
