### Step-by-Step Solution 1. **Identify the Type of Compounds**: - When small atoms like Hydrogen (H), Carbon (C), and Nitrogen (N) get trapped inside the crystal lattice of transition metals, they form **interstitial compounds**. 2. **Physical Characteristics of Interstitial Compounds**: - **Hardness**: Interstitial compounds are very hard compared to the pure metals from which they are formed. - **Melting Points**: They have higher melting points than the pure metals. This means that the melting point of an interstitial compound is greater than that of the transition metal it is derived from. ...

Compounds formed when the noble gases get entrapped in the cavities of crystal lattices of certain oreganic and inorganic compounds are known as

Assertion: All clatharate compound of noble gas are the compounds in which the molecules of noble gases are trapped in cavities in te crystal lattice of other compounds. Reason: He and Ne having smaller size do not form clathrate compound molecules because they are small enough to escape from cavities.

In an ideal crystal, the entropy of the constituents at absolute zero temperature (0K) is zero. However, the crystals generally suffer from certain defects also called imperfections They may be both electronic and atomic in nature. The atomic imperfections may be stoichiometric (Schottky and Frenkel defects) or non-stoichiometric (metal excees and metal deficiency defects). In addition to these, there are impurity defects which are caused by the addition of certain impurities of metals and this is known as dopping. The dopping leads to semi conductors which may be either n-type or p-type in nature. In stoichiometric defects, the ratio of positive and negative ions as indicated by chemical formula of the compound:

Compound (A) on reaction with iodine in the solvent diglyme gives a hydride (B) and hydrogen gas. The product (B) is instantly hydrolysed by water or aqueous alkali forming compound ( C) and liberating hydrogen gas. The compound ( C) in aqueous solution behaves as a week mono basic acid. But in presence of certain organic polyhydroxy compound behaves as a strong monobasic acid. The hydride (B) in air catches fire spontaneously forming oxide which gives coloured beads with transition metal compounds. Which of the following statement is correct for the product (C) ?

Oxidation number is the charge which an atom of an element has in its ion or appears to have when present in the combined state. It is also called oxidation state. Oxidation number of any atom in the elementary state is zero. Oxidation number of a monoatomic ion is equal to the charge on it. In compounds of metals with non metals, metals have positive oxidation number while non metals have negative oxidation numbers. In compounds of two difference elements, the more electronegative element has negative oxidation number whereas the other has positive oxidation number. In complex ions, the sum of the oxidation number of all the atoms is equal to the charge on the ion. If a compound contains two or more atoms of the same element, they may have same or different oxidation states according as their chemical bonding is same or different. A compound of Xe and F is found to have 53.3% Xe (atomic weight =133). Oxidation number of Xe in this compound is
