Find two compounds in Model $2$ that contain the prefix "mono$-"$ in their names.

a$.$ List the formulas and names for the two compounds.

b$.$ What is different about the spelling of the prefix meaning "one" in these two names?

Identify any remaining names of compounds in Model $2$ where the prefixes that do not exactly

match the spelling shown in the prefix table.

Use your answers to Questions $9-11$ to write a guideline for how and when to modify a prefix

name for a molecular compound. Come to a consensus within your group.

Would the guideline you wrote for Question $12$ give you the correct name for $N{I}_3$ as it is given

in Model $2?$ If not, modify your guideline to include this example.

All of the compounds listed in Model $2$ are binary molecular compounds. Compounds such as

$C{H}_{3}OH$ or $P{F}_{2}C{l}_3$ are not binary, and compounds such as NaCl or $CaC{l}_2$ are not molecular.

Propose a definition for "binary molecular compounds."

Collaborate with your group members to write a list of rules for recognizing and naming binary

molecular compounds from their chemical formulas.

For each of the following compounds, indicate whether or not your naming rules from Question

$15$ will apply. If not, explain why the naming rules do not apply.

$Fe{I}_3$

$IC{l}_5,HBr{O}_4$

Using the rules your group developed in Question $15,$ name each of the following molecular

compounds.
