Students are almost finished with their investigation of compound properties. As shown in the table below, the only step they have yet to complete is to decide whether HCl is ionic or covalent.
Compound/ Formula Melting/ Point Boiling/ Point Conductive in Solution? Ionic or cov
CCl4 /-23°C /77°C/ No/ Covalent
MgO /2852°C /3600°C /Yes /Ionic
HCl /-85°C /-114°C /Yes
KBr /734°C /435°C /Yes /Ionic
Select which statement correctly completes the table and contains a correct conclusion based on the information in the above table.
A.
HCl is an ionic compound. This table demonstrates that ionic compounds have much higher melting and boiling points than covalent compounds.
B.
HCl is a covalent compound. This table demonstrates that ionic compounds are electrically conductive in solution while covalent compounds are not.
C.
HCl is an ionic compound. This table demonstrates that ionic compounds are electrically conductive in solution while covalent compounds are not.
D.
HCl is a covalent compound. This table demonstrates that ionic compounds have much higher melting and boiling points than covalent compounds.
