MCQ
The size of the following species increases in the order
- ✓$M{g^{2 + }} < N{a^ + } < {F^ - } < Al$
- B${F^ - } < Al < N{a^ + } > M{g^{2 + }}$
- C$Al < Mg < {F^ - } < N{a^ + }$
- D$N{a^ + } < Al < {F^ - } < M{g^{2 + }}$
✓
Answer
Correct option: A.
$M{g^{2 + }} < N{a^ + } < {F^ - } < Al$
a
(a) $M{g^{2 + }} < N{a^ + } < {F^ - } < Al$
(a) $M{g^{2 + }} < N{a^ + } < {F^ - } < Al$
${F^ - }$ has bigger size than $M{g^{2 + }}$ and $N{a^ + }$ due to small nuclear charge.
