What are the others examples of NaCl type ionic salts ?

Most of the halides of alkali metals, oxides and sulphides of alkaline earth metals have this type of structures.

(1) Group 1^st Halides ie NaI, KCl, RbI, RbF ( except Cs halides) .

(2) Group 2^nd  oxide   MgO, CaO, BaO, SrO ( except BeO)

(3) Ammonium Halides ie NH₄Cl ,NH₄Br ,NH₄I etc

(4) Silver Halides ie AgF, AgCl, AgBr ,( except AgI)

(5) Other examples , TiO ,FeO, NiO etc

 

Note: Ferrous oxide also has sodium chloride, types structure in which O^-2 ions are arranged in ccp and Fe⁺² ions occupy octahedral ions. However, this oxide is always non – Stoichiometric and has the composition Fe_0.95 O  It can be explained on the assumption that some of the Fe⁺² ion are replaced by 2/3^rd as many Fe⁺³ ions in the octahedral voids.

Graphite is considere, thermodynamically the most stable allotrope of carbon why ?

Thermodynamically the most stable allotrope of carbon is considered to be graphite. This is due standard enthalpy of formation of graphite is taken zero .while enthalpy of formation of diamond and fullerenes are 1.90 KJ/Mole and 38.1 KJ/Mole respectively.
