NEETChemistryPeriodic Table and PeriodicityMCQ+4 / −1
Which of the following represents the correct order of increasing electron gain enthalpy with negative sign for the elements O, S, F and Clll ?
  1. A
    Clll < F < O < S
  2. B
    O < S < F < Clll
  3. C
    F < S < O < Clll
  4. D
    S < O < Clll < F
View written solutionFree

Correct answer: B

Cl atom has the highest electron affinity in the periodic table. F is a member of group 17 has highest electron gain enthalpy than S which is a group 16 element. This is turn is higher than the electron affinity of O atom. Thus,

Cl > F > S > O
