Vedclass · Answer

(A) Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself in a chemical bond. Across a period in the periodic table,from left to right,the effective nuclear charge increases and the atomic size decreases,leading to an increase in electronegativity. The elements $C$,$N$,$O$,and $F$ belong to the second period of the periodic table. Their positions from left to right are $C$ (Group $14$),$N$ (Group $15$),$O$ (Group $16$),and $F$ (Group $17$). Therefore,the increasing order of electronegativity is $C < N < O < F$.

The correct increasing order of the electronegativity is
