general properties of ionic compounds

General Properties of Ionic Compounds - The general properties of ionic compounds a..

Physical state Ionic compounds do not exist in the form of independent molecules but exist in the form of ions in crystalline solids, according to X-ray studies. These ions are arranged to form the crystal lattice in definite geometric pattern. For example, in NaCl ..

The main characteristic properties of covalent compounds a..

Alkenes are more reactive than alkanes due to the presence of a double bond. The carbon-carbon double bond consists of a strong bond and a weak p bond. The typical reactions of alkenes involve the breaking of this weaker p bond, viz., and formation of two sigma ( s ) bonds...

Comparison of Properties of Electrovalent and Covalent Compounds Property Electrocalent or ionic compounds Covalent or molecular compounds Structure of charged ions They consist of oppositely charged molecules They ..

The covalent compounds do not exist as ions but they exist as molecules They exist at room temperature, as liquids or gases. However, a few compounds also exist in the solid state e.g. urea, sugar, etc. The melting and boiling points of covalent compounds are ..

Factoids - A chemical compound is always electrically neutral. The positive and negative valencies of the ions/radicals in a compound are equal and balance..
