The most electronegative element is

which is the most electronegative element ?

The most and the least electronegative element paris among the following is :

The concept of electronegativity (EN) is mainly to discuss the nature of chemical bonding, EN of an atom is the measure of its capacity to attract the shared electron pair towards itself. Linus Pauling compiled the values of EN that are most widely used, and that are displayed for a few elements in Table - 1. These values are based on bond energy differences between atoms bonded to themselves (e.g. A-A) and to other atoms (e.g. A-B), and an arbitary value of 4 to fluorine (most electronegative element) Mulliken regarded electronegativity as the average value of ionization energy and electron affinity of an atom EN= 1/2 (IE+EA). Both IE and EA are expressed in electron volts. In the Table-2, values of IE and EA for several elements are listed Table-3 shows the values of dipole moments and bond energies for simple molecules. Based upon the electronegativity difference of bonded atoms, which of the following about the chemical bond?

Mesomerism is extended resonance. Atoms or groups with lone pairs of electrons release electrons when connected to doubly bonded carbons. It is +M effect. Unsaturated groups when connected to doubly bonded carbons withdraw pi electrons from the doubly bonded carbons. It is -M effect. Here the double bond is the unsaturated group should be between less electronegative atom and more electronegative atom. Which of the following is most stable?
