Select correct order(s) of electronegativity of element is/are:

Options

A. Paulling scale (E.N. of F-atom)gtMulliken scale (E.N. of F-atom)
B. `Cl_(2)O_(7)` (E.N. of Cl-atom) `gtCl_(2)O_(5) ` (E.N. of C-atom)
C. `CH_(4)` (E.N. of C-atom) `gtCO_(2)` (E.N. of C-atom)
D. `Cu^(2+)` (E.N.) `gtCu^(+)` (E.N.)

Answer

A, B, D

Explanation

Electronegativity of central atom is directly proportional to oxidation states.
