Practice question from Classification of Elements and Periodicity in Properties (NEET Preparation Chemistry), with the correct answer and a step-by-step solution.
easy · MCQ · Q-5BD3A8
The correct order of electronegativity values on the Pauling scale for the elements F, Cl, Br, and I is:
- A.F > Cl > Br > ICorrect answer
- B.F > Cl > I > Br
- C.Cl > F > Br > I
- D.F > Br > Cl > I
Solution
Electronegativity decreases down a group in the periodic table. For the halogens, the Pauling electronegativity values are F (4.0), Cl (3.0), Br (2.8), and I (2.5). Thus, the correct order is F > Cl > Br > I.
