The order of negative electron gain enthalpy of $\mathrm{Li}, \mathrm{Na}, \mathrm{S}, \mathrm{Cl}$ is

• A

  $\mathrm{Na}>\mathrm{S}>\mathrm{Cl}>\mathrm{Li}$
• Correct answer
  B

  $\mathrm{Cl}>\mathrm{S}>\mathrm{Li}>\mathrm{Na}$
• C

  $\mathrm{Cl}>\mathrm{Li}>\mathrm{S}>\mathrm{Na}$
• D

  $\mathrm{Li}>\mathrm{Na}>\mathrm{S}>\mathrm{Cl}$

Hence, the correct answer is option: 'B'.
