Explain how the ionic character in a covalent bond is related to elect

1.	Explain how the ionic character in a covalent bond is related to electronegativity?
Answer» Solution :(i) The extent of ionic character in a COVALENT bond can be related to the electronegativity ditference of the bonded atoms. (ii) In a typical polar molecule `A^(DELTA-)-B^(delta+),` the electronegativity difference `(X_(A)-X_(B))` can be used to predict the percentage of the 1onic character as follows: (iii) If the electronegativity difference `(X_(A)-X_(B))` is EQUAL to 1.7, then the bond A - B has 50% ionic charecter. (iv) Ifit is greater than 1./. then the bond A - B has more than 50% ionic charecter. (v) Ifit is lesser tha 1 . 7 , then the bond A - B has LESS than 50% ionic charecter.
