Is Potassium bromide (KBr) polar or non-polar? – Polarity of KBr
The question is –
Is KBr polar or nonpolar?
Answer:
⇒ KBr is a polar ionic compound.
Explanation:
Potassium bromide (KBr) is polar as it is an ionic compound composed of oppositely charged potassium (K+) and bromide (Br–) ions, held together by strong electrostatic forces of attraction.
All ionic compounds are polar with high electronegativity differences between the concerning atoms.
Alkali metals, such as potassium, are electropositive in nature.
Thus, these possess low electronegativity values.
On the other hand, halogens such as bromine are strongly electronegative.
An electronegativity difference of 2.14 units exists between potassium (E.N = 0.82) and bromine (E.N = 2.96) in each K+ Br– unit cell.
The K+ Br– bond thus possesses a high dipole moment value (symbol µ).
Consequently, KBr is a polar ionic compound.
