ARELLANO UNIVERSITY COLLEGE OF PHARMACY Pharmaceutical Inorganic Chemistry Laboratory INORGANIC COMPOUNDS Name: Jasmine Ann B. Galagala Date: September 7, 2024 Student Number: 24-01515 Questions: 1. What is the general difference between ionic and covalent binary compounds, and how does their bonding nature affect their physical properties? Ionic binary compounds consist of metal and non-metal ions and has a complete exchange of electrons whereas covalent binary compounds are molecules with two non-metals that share electrons. The strong bonds between ions in the ionic binary compound affects its physical properties, where it has a high melting and boiling points, low conductivity in solid solid state, and high conductivity in aqueous solutions. Meanwhile, covalent binary compounds have physical properties that has a lower melting and boiling point and electrical conductivity than ionic compounds. 2. How does the presence of three different elements in a ternary compound influence the complexity of its structure compared to binary compounds? The ternary compound has a more complex structure than a binary compound because it has three different elements whereas the binary only has 2. 3. In coordination compounds, what role do ligands play in determining the geometry and stability of the complex, and how is this different from simple binary or ternary compounds? Coordination compounds consist of an array of anions or neutral atoms that are bound to a central metal atom. These atoms and ions that are bound are called ligans. Ligans within the coordination sphere affects the geometry around the metal center and a stronger ligand has more stability of the complex than weaker ones. Unlike binary or ternary compounds, coordination compounds have a more complex structure since it they have multiple groups of atoms. 4. How do the naming conventions differ between binary, ternary, and coordination compounds in IUPAC nomenclature? The IUPAC nomenclature have different naming conventions to binary, ternary and coordination compounds. In naming binary compounds, the first element is given by its element name, then the second is given its root element name and followed by -ide. For ternary compounds, the cation is stated first followed by the anion. Meanwhile, coordination compounds are named by, first stating the cation. Then listing all the ligands alphabetically. However, if the coordination sphere is an anionic, we put the suffix -ate. 5. How does the reactivity of coordination compounds differ from that of binary and ternary compounds due to the involvement of central metal ions and complex formation? Due to the central metal ions and complex formation of coordination compounds they generally react to a solution through substitution, which is the exchange of reactions of the attached ligands with other reactive ligands. The coordination complexes with low activation energy have a high reactivity and have a rapid ligand exchange in a solution. Binary and ternary compounds do not have ligands and does not exhibit the same reactivity as coordination compounds.
