Question

What types of compounds are CaCl2, Cu, C2H6, respectively.

Answer 1

Answer:

Ionic, metal, organic

Explanation:

In this case, we have to analyze each compound:

-) $CaCl_2$

In this compound, we have a non-metal atom (Cl) and a metal atom (Ca) . So, we will have a high electronegativity difference between these atoms, With this in mind, we will have an ionic bond. Ions can be produced:

$CaCl_2~->~Ca^+^2~+~2Cl^-$

The cation would be $Ca^+^2$ and the anion is $Cl^-$. So, we will have an ionic compound.

-) $Cu$

In this case, we have a single atom. If we check the periodic table we will find this atom in the transition metals section (in the middle of the periodic table). So, this indicates that Cu (Copper) is a metal.

-) $C_2H_6$

In this molecule, we have single bonds between carbon and hydrogen. The electronegativity difference between C and H are not high enough to produce ions. So, with this in mind, we will have covalent bonds. This is the main characteristic of organic compounds. (See figure 1)

Answer 2

CaCl₂, Cu, C₂H₆ are ionic, metal, and organic compounds, respectively.

CaCl₂ is formed by a metal (Ca) and a non-metal (Cl). Due to the difference in their electronegativities, they form ionic compounds. These compounds tend to have high melting and boiling points and conduct electricity in aqueous solution.

Cu is a transition metal. It is a good electric and heat conductor, which is why it is used in cables. It also has high melting and boiling points.

C₂H₆ (ethane) is a hydrocarbon, that is, an organic compound (formed by at least C and H). They are bad conductors and have low melting and boiling points.

CaCl₂, Cu, C₂H₆ are ionic, metal, and organic compounds, respectively.
