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.
