Assertion (A) Separation of Zr and Hf is difficult. Reason (R ) Because Zr and Hf lie in the same group of the Periodic Table.

The lanthanide contraction is responsible for the fact that (a)Zr and Yt have about the same radius (b)Zr and Nb have smaller oxidation state (c)Zr and Hf have about the same radius (d)Zr and Zn have the same oxidation state.

Assertion :- When the muscle fibre contracts, sacromere length is reduced. Reason :- Sliding of myosin filament occurs due to rotational movement of myosin head.

How would you account for the following? (i) Transition metals exhibits variable oxidation state. (ii) Zr(Z=40) and Hf(Z=72) have almost identical radii. (iii) Transition metals and their compounds act as catalyst. OR Complete the following chemical equation: (i) Cr_(2)O_(7)^(2-)+6Fe^(2+)+14H^(+)rarr (ii) CrO_(4)^(2-)+2H^(+)rarr (iii) 2MnO_(4)^(2-)+5C_(2)O_(4)^(2-)+16H^(+)rarr

Zr(Z=40) and Hf(Z=72) have similar atomic and ionic radii because of:

The formation of diasteromers allows the separation of enantiomers (called resolution) which is not easy as enantiomers have identical physical properties. One general with naturally occurring chiral molecule to form a pair of diastereomers. These can be separated easily as they have different physical properties. If the original chemical reaction can be reversed, the enantiomers can be isolated. Which of the following is an example of diastereomers ?
