Question

Incorrect order of properties given in parenthesis are (A) Cl>S>F>O (Electron affinity) (B) O>F>B>C (I E2) (C) N>O>P>S (I E1) (D) O>C>B>N (Electron affinity)

Tardigrade Admin · Accepted Answer

The second element in each group in the periodic table has higher electron affinity than the other respective group elements and in a period from left to right electron affinity increases.
Correct order is:

Cl > F > S > O

Q. Incorrect order of properties given in parenthesis are

$Cl > S > F > O$ (Electron affinity)

$O > F > B > C$ $(I E_{2})$

$N > O > P > S (I E_{1})$

$O > C > B > N$ (Electron affinity)

The second element in each group in the periodic table has higher electron affinity than the other respective group elements and in a period from left to right electron affinity increases.
Correct order is:
$Cl > F > S > O$
