[" Ionic compounds generally "],[" have "]

Covalent compounds generally have :

Ionic solids are generally

An ionic compound is :

Ionic compounds in general posses.

Give reasons for the following: a. Ionic compounds in general have high melting and boiling points. b. Highly reactive metals cannot be obained from their oxides by heating them with carbon. c. Copper vessel get a green coat when left exposed to air in the rainy season.

(i) Carbonate and sulphide ores are usually converted into oxides during the process of extraction of metals. (ii) Ionic compounds have generally high melting points. (iii) Hydrogen is not a metal but is has been assigned a place in the reactivity series of metals. (iv) The galvanised iron article is protected against rusting even if the zinc layer is broken.

Ionic compounds in general possess both

Ionic compounds are generally soluble ini benzene.
