Answer #1

Electronegativity; The tendency to attracted the bond pair of electrons in covalent bond is called electronegativity.

Pauling scale :pauling calculate electronegativity of elements based on bond dissociation energy.

XA-XB = 0.208

XA ,XB are electronegativity of A,B element

is bond energy difference between experimental value and calculated value

   = EA-B -1/2[EA-A + EB-B]

Hydrogen is reperance element H = 2.1

                  H-F

flurine electronegative value = 4

    electronegtive difference = 4-2.1 = 1.9
