Assertion Among two cations of similar size the polarising power of cation with pseudo noble gas configuration is larger than cation with noble gas configuration Reasoning Polarising power of `Ag^(o+)` is more than `K^(o+)` .A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`B. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`C. If `(A)` is correct but `(R )` is incorrectD. If `(A)` is incorrect but `(R )` is correct |

Answer» Correct Answer - A Cations with pseudo gas configuration has high `Z_(eff)` than cation with nodal gas conguration due to the presence of d-orbitals hence `Ag^(o+)` ion having more `Z_(eff)` than `K^(o+)` and is smaller than `K^(o+)` ion . |
