Cations are present in the interstitial sites in which defect?

The questions given below consist of an assertion and the reason. Use the following key to choose the appropriate answer. (a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion. (b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.(c) Assertion is is CORRECT but reason is INCORRECT. (d) If assertion is INCORRECT but reason is CORRECT. (e)If both assertion and reason are INCORRECT. Assertion: In ZnO the excess Zn^(2+) ions are present interstitial sites. REason: Metal excess crystals have either missing cation or anin in intertitial site.

In a solid lattice the cation has left a lattice site and is located at an interstitial position, the lattice defect is

Ionic lattic has two major points defects ,(1) Schottky (2) Frenkel defects . Schottkly defects occurs due to the cations - anion pair's missing from the lattice sites . Frenkel defects occurs when smaller ion leaves from its lattic site and fits into an intersitial space.which defect decrease density of the crystal ?

Define the following : Interstitial defect

Define restriction site.

When anion leaves the normal lattice site and electron occupies interstitial sites in its crystal lattice, It is called:

What are interstitial sites ? Discuss tetrahedral and octrahedral interstitial sites in a close packed arrangment.

Amino acids serine, aspartic acid and phenylalanine are present on the active site of an enzyme. Explain which forces may be involved in binding the drug to the enzyme if the drug inhibits the holding of substrate on the active site of enzyme .
