When compared to compound B, compound A has lower melting and boiling points and vaporizes more readily. Is compound A an ionic compound or a molecular compound?

A. Ionic
B. Molecular

I say B

true

NaOH+HCL

To determine whether compound A is an ionic compound or a molecular compound, we can consider its properties. The given information states that compound A has lower melting and boiling points and vaporizes more readily compared to compound B.

Ionic compounds are formed by the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions. They generally have higher melting and boiling points due to the strong electrostatic forces between the ions.

On the other hand, molecular compounds are formed by the sharing of electrons between atoms. They typically have lower melting and boiling points and tend to vaporize more readily, as the intermolecular forces holding the molecules together are generally weaker.

Since compound A has lower melting and boiling points and vaporizes more readily, it exhibits properties consistent with a molecular compound. Therefore, the correct answer is B.
