Is the octet rule satisfied for each atom or ion?
Check your neighbor, or ask instructor to work some of these in class. 14. Draw Lewis structures for each of the following compounds: Cl2, HCN, NCl3, C2H4, C2H2 Check your neighbor, or ask instructor to work some of these in class. 15. Using the system of prefixes, name the following molecular compounds: SiO2, silicon dioxide; SO2, sulfur dioxide; CCl4, carbon tetrachloride; N2O3, dinitrogen trioxide; CCl4 , carbon tetrachloride; SF4 , sulfur tetrafluoride; SF6, sulfur hexafluoride; P2O5, diphosphorus pentoxide; XeF4 Xenon tetrafluoride. 16. When a positively charged plastic comb is brought close to a stream of water, the water is deflected by the comb. Using the electronegativity difference between hydrogen and oxygen, explain why this phenomenon occurs. The water molecule’s polar covalent bond results in the molecule having a partial positive end (at the hydrogens) and a partial negative end (at the oxygen). The negative end is attracted to the positively charged comb. 17. Draw the L
