Question

(TURN IN BEFORE LAB) Date: Section: Student Name 1. Describe the bond that holds an ionic compound together 2. How is a bond that holds a molecular compound together different from #1 above. 3. What kind of compound uses prefixes in naming? What kind of compound sometimes uses Roman numerals in naming? In what specific type of situation are they needed? 4. Experiment 6 Molecular and lonic Compounds: Packages, Puzzles and Paradigms 91

Answer 1

Ionic compounds composed of positively charged colour and negatively charged anion the electrostatic attraction between cation and anion hold the ionic compounds together Nacl: Na cl caso4: Cu^2 + so^24 Na3po4: 3 Na + po^3_4 Bond that hold a molecular compounds together are hydrogen bond Due to different in the elect negativity of �O� and �H� bond gets polarized oxygen being more electronegative pull the electron density towards it and become partly are charged (sn) and H get partial positively charged Sn these polarized bond result a secondary intersection call hydrogen bond Hetero polyatomic covalent compounds uses predefines naming Eg compounds /C02 structure/0 = c = 0 name carbon dioxide In organic compound having oxidation state uses roman numerals in naming to state oxidation number of metal ion
