Question

Question:

Rank these bonds from most ionic to most covalent in character Most ionic most covalent K-F , F-F, Br-F, Cl-F , Ca-F

Answer:

Electronegativity
Electronegativity is the property of a molecule attached to another particle that characterizes the propensity of that iota to draw in the reinforced pair electrons towards itself. More prominent the electronegativity distinction between reinforced molecules, more prominent will be the extremity of the bond.

Explanation:
Request of the bonds from most ionic to least ionic is
K−F>Ca−F>Br−F>Cl−F>F−F
This is chosen the premise of the electronegativity contrast between the reinforced molecules.
K (Potassium) has the least electronegativity while F is the most electronegative molecule.
Thus, the bond framed between them is generally polar.
While the least polar or most covalent bond is F-F since electronegativity contrast is zero for this situation.
In Ca-F, Calcium is additionally metal however it is less metallic than potassium. In this way, it will be second-generally polar.
In Br-F, Electronegativity distinction is very huge however littler than that with metals.

  1. Electronegativity
    Electronegativity is the property of a molecule attached to another particle that characterizes the propensity of that iota to draw in the reinforced pair electrons towards itself. More prominent the electronegativity distinction between reinforced molecules, more prominent will be the extremity of the bond.
