Out of the following, the alkene that exhibits optical isomerism is
2–methyl–2–pentene
3–methyl–2–pentene
4–methyl–1–pentene
3–methyl–1–pentene
D.
3–methyl–1–pentene
3-methyl-1-pentene is optically active due to presence of chiral carbon, indicated by red star

Indicate the type of isomerism exhibited by the following complexes and draw structures for these isomers:
(i) K[Cr(H2O)2(C2O4)2], (ii) [Co(en)3Cl3,
(iii) [Co(NH3)5(NO2)]|NO3]2, (iv) [Pt(NH3)(H2O)Cl2]
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.
