Question

The correct order of increasing polarising power
of the cations in `AlCl_(3), MgCl_(2) and NaCl` is
A. `AlCl_(3) lt MgCl_(2) lt NaCl`
B. `MgCl_(2) lt NaCl lt AlCl_(3)`
C. `NaCl lt MgCl_(2) lt AlCl_(3)`
D. `NaCl lt AlCl_(3) lt MgCl_(2)`

Answer 1

Correct Answer - C
Polarising power of cations increases with the
increasing charge
`{:(""(+1),(+2),(+3) ),(NaCl lt ,MgCl_(2), ltAlCl_(3)):}`
