Fluorine is more electronegativity than ...

Fluorine is more electronegativity than nitrogen. The best explanation is that:

A

the valency electrons in F are on the average, a little farther to the nucleus than in N

B

the charge on a F nucleus is `+9`, while that on N nucleus is `+7`

C

the nitrogen has half filled valence shell electron configuration, `ns^(2)np^(3)` where as fluorine has partially filled electron configuration `ns^(2)np^(5)`

D

the electronegativity decreases from top to bottom in each of the group as the effect nuclear charge remains constant.

  • Fluorine is more electronegative than nitrogen the best explanation is that

    A
    the avlence electron in F are on an average a little closer to the nucleus than in N
    B
    the charge of a F nucleus is +9 while that on N nucleus is +7
    C
    The valence electrons in F and N are in different shells and thus their energy are greatly different
    D
    electronegativity increase from left to right in each of the period

  • Assertion: Although fluorine is more electronegative than chlorine, yet p-flurobenzoic acid is a weaker acid than p-chlorobenzoic acid. Reason: Due to matching sizes of 2p-orbitals of F and carbon, F has a stronger +R-effect than Cl.

    A
    if both assertion and reson are true, and reason is the true explanation of the assertion.
    B
    If both assertion and reason are true, but reason is not the true explanation of the assertion.
    C
    if assertion is true, but reason is false.
    D
    If both assertion and reason are false.
