Which one of the following order is correct ?

Options

A. `K^(+)ltCa^(2+)ltP^(3-)ltS^(2-)` Ionic size
B. `Na_(aq.)^(+)gtK_(aq.)^(+)gtRb_(aq.)^(+)gtCs_(aq.)^(+)`: Electrical conductance
C. `Al_(aq.)^(3+)gtMg_(aq.)^(2+)gtNa_(aq.)^(+)`: Hydrated size
D. `I_(aq.)^(-)ltBr_(aq.)^(-)gtCl_(aq.)^(-)gtF_(aq.)^(-)`: Ionic mobility

Answer

C

Explanation

(a)`Ca^(2+)ltK^(+)ltS^(2-)ltP^(3-)`: Ionic size
(b)`Na_(aq)^(+)gtK_(aq)^(+)gtRb_(aq)^(+)gtCs_(aq)^(+)`: Electrical conductance
(c) `I_(aq)^(-)ltBr_(aq)^(-)gtCl_(aq)^(-)ltF_(aq)^(-)`: Ionic mobility
