Ch.22 - The Main Group Elements
Chapter 22, Problem 16
Give one example from main-group chemistry that illustrates each of the following descriptions. (a) Covalent network solid (b) Disproportionation reaction (c) Paramagnetic oxide (d) Lewis acid (e) Amphoteric oxide (f) Semiconductor (g) Strong oxidizing agent (h) Allotropes
Verified step by step guidance1
(a) Covalent network solid: Consider silicon dioxide (SiO₂), which forms a three-dimensional network of covalent bonds, resulting in a very hard and high melting point solid.
(b) Disproportionation reaction: An example is the reaction of chlorine gas in water, where chlorine is both reduced and oxidized: Cl₂ + H₂O → HCl + HClO.
(c) Paramagnetic oxide: Manganese(IV) oxide (MnO₂) is paramagnetic due to the presence of unpaired electrons in the d-orbitals of manganese.
(d) Lewis acid: Aluminum chloride (AlCl₃) acts as a Lewis acid because it can accept an electron pair, often forming a complex with a Lewis base.
(e) Amphoteric oxide: Zinc oxide (ZnO) can react with both acids and bases, demonstrating its amphoteric nature.
