As ethylenediamine is added to a solution of (Compound 1) [Ni(H20)¿J²*, the water molecules are replaced two at a time by ethylenediamine to produce the sequence of ions: (Compound 2) [Ni(en)(H20)4]²*, (Compound 3) [Ni(en)2(H20)2]2*, and (Compound 4) [Ni(en)a]²*. Note: atomic number of Ni is 28. Which of the following statements is TRUE? Select one: O a. Only compound 4 [Ni(en)3]2*can be optically active. O b. Only (Compound 3) [Ni(en)2(H20);]?* can be optically active. Oc. Compound 3 and Compount 4 have isomers which are optically active. O d. All of the mentioned four Ni compounds have isomers whose mirror images are non-superimposable (i.e.Compounds 1,2, 3, 4 are optically active). e. Compounds 1 [Ni(H2O)6]²*and 2 [Ni(en)(H20)4]²+ have isomers which are optically active.

Question
As ethylenediamine is added to a solution of (Compound 1) [Ni(H20)¿]²*, the water molecules are replaced two
at a time by ethylenediamine to produce the sequence of ions:
(Compound 2) [Ni(en)(H20)4]²*,
(Compound 3) [Ni(en)2H20)2]2*, and
(Compound 4) [Ni(en)3]?*. Note: atomic number of Ni is 28.
Which of the following statements is TRUE?
Select one:
a. Only compound 4 [Ni(en)3]2*can be optically active.
O b. Only (Compound 3) [Ni(en)2(H20)2]2* can be optically active.
c. Compound 3 and Compount 4 have isomers which are optically active.
O d. All of the mentioned four Ni compounds have isomers whose mirror images are non-superimposable
(i.e.Compounds 1, 2, 3, 4 are optically active).
e. Compounds 1 [Ni(H20)6]²*and 2 [Ni(en)(H20)4]²* have isomers which are optically active.
