Electronic configuration of four elements A, B, C and D are given below :
(A) $1 s^2 2 s^2 2 p^3$
(B) $1 s^2 2 s^2 2 p^4$
(C) $1 s^2 2 s^2 2 p^5$
(D) $1 s^2 2 s^2 2 p^2$
Which of the following is the correct order of increasing electronegativity (Pauling's scale)?
Solution
<p>The electronic configurations of four elements, A, B, C, and D, are presented as follows:</p>
<p><p>(A) $1s^2 2s^2 2p^3$</p></p>
<p><p>(B) $1s^2 2s^2 2p^4$</p></p>
<p><p>(C) $1s^2 2s^2 2p^5$</p></p>
<p><p>(D) $1s^2 2s^2 2p^2$</p></p>
<p>To determine the correct order of increasing electronegativity according to Pauling's scale, analyze the elements as follows:</p>
<p><p>Nitrogen ($1s^2 2s^2 2p^3$): Electronegativity = 3.0</p></p>
<p><p>Oxygen ($1s^2 2s^2 2p^4$): Electronegativity = 3.5</p></p>
<p><p>Fluorine ($1s^2 2s^2 2p^5$): Electronegativity = 4.0</p></p>
<p><p>Carbon ($1s^2 2s^2 2p^2$): Electronegativity = 2.55</p></p>
<p>The correct order of increasing electronegativity is:</p>
<p>Carbon (D) < Nitrogen (A) < Oxygen (B) < Fluorine (C)</p>
