Chemistry - PERIODIC TABLE Question with Solution | TestHub
On study it is seen that the electronegativity of the atom linearly increases with the partial ionic charge (q). Thus electronegativity can be written as, , where large and soft atoms have low value of b , while small and hard atoms have a large value of , and is constant, then which of the following given plot describes the electronegativity variation of F and C accurately? [Given : and ]
Options:
Answer:
Solution:
Based on the given linear relationship :
The constant represents the y-intercept (when ), meaning both lines must originate from the same point on the vertical axis.
The variable represents the slope of the line, where smaller and harder atoms have a larger value of . Since Fluorine (F) is smaller and harder than Chlorine (Cl), its slope must be steeper ().
Option (D) accurately depicts both curves starting from the same intercept with the curve for F rising more sharply than Cl.
