Hydrate Isomerism

Q.

Match List-I with List-II:

Column 1	Column 2
[Co(NH3)6] [Cr(CN)6]	Linkage isomerism
[Co(NH3)3 (NO2)3]	Solvate isomerism
[Cr(H2O)6]Cl3	Coordination isomerism
cis-[CrCl2(ox)2]3-	Optical isomerism

Q. Which of the following polymer is condensation as well as cross-linked polymer?

1. Bakelite
2. Nylon-6, 6
3. Nylon-2, Nylon-6
4. Dacron

Q. The hydrate isomer of $\left[Cr\right(H_{2}O{)}_{5}Cl]C{l}_2.H_{2}O$ is/are

1. $\left[Cr\right(H_{2}O{)}_{4}C{l}_2]Cl.2H_{2}O$
2. $\left[Cr\right(H_{2}O{)}_{3}C{l}_3]3H_{2}O$
3. All of the above.
4. $\left[Cr\right(H_{2}O{)}_6]C{l}_3$

Q. One of the most important properties of `d`-block metal cations is the formation of coordinate compounds. Widely used theories that explain bonding in these compounds are valence bond theory and crystal field theory.
The incorrect option for the complex compounds $\left[Co\left(SCN\right){\left(H_{2}O\right)}_5\right]{\left(N{O}_3\right)}_2\text{and}\left[Co\left(N{O}_3\right){\left(H_{2}O\right)}_5\right]\left(SCN\right)\left(N{O}_3\right)$ is:

1. Both are ionization isomers
2. They can exhibit hydrate isomerism
3. They can exhibit linkage isomerism
4. They do not show stereoisomerism
