MCQEasyJEE 2023Electron Gain Enthalpy & Electronegativity

The correct order of electronegativity for given elements is:

Answer

Correct answer:D

Standard Method

Given: The order of electronegativity is to be identified for $P$ , $Br$ , $C$ , and $At$ .

Find: The correct decreasing order of electronegativity.

Electronegativity is the ability of an atom to attract electrons in a chemical bond. Based on Pauling's scale:

Br = 2.8, \quad C = 2.5, \quad At = 2.2, \quad P = 2.1

Thus, the order is:

Br > C > At > P

Therefore, the correct option is D.

Comparing the elements only by period or group position without using known electronegativity values is incorrect. For this question, the Pauling scale values given in the solution should be used to arrange them correctly.
Assuming that a heavier halogen must always have higher electronegativity than carbon is incorrect. Here, $Br$ is more electronegative than $C$ , but $At$ is less electronegative than $C$ , so the actual values must be compared carefully.
