Consider the following statements and arrange in the order of the true/false as given in the codes.`S_1`:The IUPAC name of the compound `[Cr(NH_3)_5(NCS)][ZnCl_4]` is pentaamminethiocyanato-N-chromate(III) tetrachlorozincate (II). `S_2`:`CoSO_4` is paramagnetic and coloured. `S_3`:`[Co(NH_3)_4 (NO_2)_2 NO_3` shows ionisation, linkage and geometrical isomerism. `S_4`:The C-O bond length in the complex `[Fe(CO)_5]` is same as that found in carbon monoxide itself.A.

Answer» Correct Answer - C `S_1`:Pentaamminethiocyanato-N-chromium(III) tetrachlorozincate (II). or Pentaammineisothiocyanatochromium(III) tetrachlorozincate (II). `S_2`: In `CoSO_4`, the oxidation state of Co is +2 i.e. `[Ar]^18 3d^7 4s^0` electrons configurations. It has two unpaired electrons so it is paramangetic and coloured. `S_3:[Co(NH_3)_4(NO_2)_2]NO_3 & [Co(NH_3)_4(NO_2)(NO_3)]NO_2` show ionisation isomerism `[Co(NH_3)_4(NO_2)_2]NO_3 & [Co(NH_3)_4(NO_2)(ONO)]NO_3` show linkage isomerism This complex has cis- and trans isomers and the total isomers are 10. `S_4`:The bond length C-O in CO itself is 1.128, while the bond length in `[Fe(CO)_6]` molecules are 1.15Å on account of synergic interaction between Fe and CO. |
