Wired Faculty App

Which of the following acids does not exhibit optical isomerism?

  • Maleic acid

  • α-amino acids

  • Lactic acid

  • Tartaric acid

Solution

A.

Maleic acid

Only those compounds exhibit optical isomerism, which has chiral centre and / Or absence of symmetry elements. (chiral carbon is the four valencies of which are satisfied by four different groups.)

Thus, maleic acid does not exhibit optical isomerism.

(i) [Co(NH3)6]Cl3
(ii) [Co(NH3)5Cl]Cl2
(iii) K3[Fe(CN)6]
(iv) K3[Fe(C2O4)3]
(v) K2[PdCl4]
(vi) [Pt(NH3)2Cl(NH2CH3)]Cl.

(i)    K[Cr(H2O)2(C2O4)2],                      (ii) [Co(en)3Cl3,
(iii) [Co(NH3)5(NO2)]|NO3]2,                 (iv) [Pt(NH3)(H2O)Cl2]

Explain on the basis of valence bond theory that [Ni(CN)4]2–  ion with square planar is diamagnetic and the [NiCl4]2– ion with tetrahedral geometry is paramagnetic.

Predict the number of unpaired electrons in the square planar [Pt(CN)4,]2– ion.

The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacynoion contains only one unpaired electron. Explain using crystal field theory.
