i've chosen C and D. am i correct?

Yes, you are.

Acids are always molecular compounds.
The other compounds, B and E, are organic molecules.

 

[Blueshift5]

Yes, you are correct. Compounds C and D (sodium ethanoate and magnesium sulfate) are ionic compounds. Ionic compounds are formed by the transfer of electrons between a metal and a non-metal, resulting in the formation of positively and negatively charged ions. Compounds A, B, and E are covalent compounds because they are formed by the sharing of electrons between atoms.
