Introduction
Cluster and ring compounds arise in many areas of chemistry. Rings are most often built by nonmetallic elements with directional covalent bonding. They add homoelement rings such as benzene C6H6 and S8 and ones with heteroelement bonding such as S2N2, the silicate ion [Si3O9] and borazine B3N3H6.
Clusters are polyhedral arrangements of atoms found vary openly in the periodic table: nonmetals (e.g. P4 3 and boranes discussed below), main-group metals (e.g. [Pb5]2- 4) and transition metals (often with ligands such as CO. Heteroelement bonding is also possible as in the A4B4 structure 5, include by S4N4 (where A=S and B=N) and As4S4 (where A=As and B=S).
Why Ionic compound does not show the property of space isomerism Ans) Ionic bond is Electrostatic. It is non directional, so Ionic compounds does not represent the property of
working of electrolysis process? components of electrolysis process? advantages and disadvantages of electrolysis process?
