Add a comment. -1. –I effect increase the bond strength and force constant, increase of bond strength is possible only by holding two atoms closer than earlier. hence -I effect reduces bond length and increases bond strength. Share. WebA covalent bond with equal sharing of the charge density has 0% ionic character, and a perfect ionic bond would of course have 100% ionic character. One method of estimating the percent ionic character is to set it equal to the ratio of the observed dipole moment to the value of eR, all multiplied by 100.
