Question

The correct sequence of electron gain enthalpy of the elements listed below is
A. Ar
B. Br
C. F
D. S
Choose the most appropriate from the options given below:

• A. C > B > D > A
• B. A > D > B > C
• C. A > B > D > C
• D. D > C > B > A

Answer 1

Answer: (B)

A > D > B > C

Answer 2

$Element$	$\Delta_{eg}$ $H$ , $(\text{kJ/mol})$
F	$-333$
S	$-200$
Br	$-325$
Ar	$+96$

Thus the correct answer is Option 2.
