Is Cyclohexane (C6H12) polar or nonpolar? - Polarity of Cyclohexane
The question is –
Is Cyclohexane polar or non-polar?
⇒ Cyclohexane (C6H12) is non-polar.
The polarity of Cyclohexane depends on the individually very weakly polar (almost non-polar) C-H bonds and symmetrical tetrahedral arrangement of all six C-atoms and twelve H-atoms in a hexagonal ring structure.
Cyclohexane (C6H12) is a cyclic structure.
The symmetrical tetrahedral molecular structure of cyclohexane consists of a central ring of 6 C-atoms that is surrounded by 12 H-atoms which are equidistant as well as at equal angles.
An electronegativity difference of 0.35 units exists between the single covalently bonded C and H-atoms in each C-H bond.
So each C-H bond is very weakly polar with a small dipole moment value.
In contrast, each C-C bond present within the ring is non-polar owing to zero electronegativity difference between the bonded atoms.
It is due to the symmetrical molecular shape and geometry that small oppositely-pointing C-H dipole moments get canceled equally.
Thus, Cyclohexane (C6H12) is overall non-polar (net µ = 0).
