Question

classify each of the following compounds as ionic or molecular. drag the appropriate compounds to their respective bins. cf₂cl₂ co kmno₄ ni₃ pb(no₃)₂ molecular ionic

Explanation:

Step1: Recall compound - type rules

Ionic compounds usually form between metals and non - metals, while molecular compounds form between non - metals.

Step2: Analyze $CF_2Cl_2$

It consists of non - metals C, F, and Cl. So it is molecular.

Step3: Analyze $CO$

It consists of non - metals C and O. So it is molecular.

Step4: Analyze $KMnO_4$

It has a metal K and non - metals Mn and O. So it is ionic.

Step5: Analyze $NI_3$

It consists of non - metals N and I. So it is molecular.

Step6: Analyze $Pb(NO_3)_2$

It has a metal Pb and non - metals N and O. So it is ionic.

Answer:

Molecular: $CF_2Cl_2$, $CO$, $NI_3$
Ionic: $KMnO_4$, $Pb(NO_3)_2$
