MCQ
Incorrect set is
$(a)$ Ionisation energy $(Na < Li < B < Be)$
$(b)$ Electron affinity $(N < P < O < S)$
$(c)$ Electron negativity $(S < O < Cl < F)$
$(d)$ Atomic radii $(F < N < O < Na)$
- A$a$
- B$a\,,\,b$
- C$a\,,b\,,c$
- ✓$c,\,d$
✓
Answer
Correct option: D.
$c,\,d$
d
${\text{E}}{\text{.N }} \Rightarrow \,{\text{F > O > Cl > S}}$
${\text{E}}{\text{.N }} \Rightarrow \,{\text{F > O > Cl > S}}$
${\text{At}}{\text{.radii }} \Rightarrow \,Na{\text{ > N > O > F}}$
