Atomic number of Crand Feare respectively 24 and 26, which of the following is paramagnetic with the spin of electron?.

Question

Accepted Answer

Correct answer: D. (d) Odd electrons, ions and molecules are paramagnetic. In C r(C O)_6 molecule 12 electrons are contributed by CO group and it contains no odd electron. C r→3 d^54 s^1 F e(C O)_5molecule also does not contain odd electron. F e→3 d^64 s^2 In [F e(C N)_6]^4− ion F e_(+2_)→3 d^64 s^0 No odd electrons. In [C r(N H_3)_6]^3+ ion C r_(+3_)→3 d^34 s^0 This ion contains odd electron so it is paramagnetic.
