POLAR AND NONPOLAR MOLECULES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Classify the following molecule as polar or nonpolar:F2
A
Polar
B
Nonpolar
Explanation: 

Detailed explanation-1: -Fluorine (F2) is a non-polar molecule. The F-F bond in the F2 molecule is non-polar due to no electronegativity difference between the bonded atoms.

Detailed explanation-2: -Explain. F2 is non polar because both the bonding atoms are same thus there is no electronegativity difference between the atoms. Thus the electron pair will lie exactly in the middle of the two atoms thus there is no generation of poles.

Detailed explanation-3: -F2 Polarity As you may have noticed, the F2 molecule is symmetric because both the constituent atoms are of the same element F, and thus there is no difference in the electronegativity of the two constituent atoms, thereby making F2 non-polar.
