Why HF is a covalent compound while elkectronegativity difference of H&F is more than 1.9?
Answer:
The difference of electronegativity is not more than 1.9.
It is 1.9 because electronegativity of F = 4.0 and electronegativity of H is 2.1
yep it IS 1.9,not more than 1.9
H-f compound electronegativity of f is very high and note that h is the least electronegative element.Here i'll give u a chart of varing electronegativity F > O > N
If the EN difference is between 1.6 and 2.0 and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.
