ChemistryChemical Bonding and Molecular StructureJEE Main

For an bond, if per cent ionic character is plotted against electronegativity difference , the shape of the curve would look like one of four sketches labelled , , , in the source (a rising curve passing through 50% near , levelling off towards 100% at large electronegativity differences, consistent with the empirical relation ). The correct curve is

Answer: (C)

Solution

Per cent ionic character is empirically related to the electronegativity difference by , a monotonically increasing function that starts at 0% when and rises steeply, approaching 100% for very large electronegativity
