Acetone is more likely to dissolve covalent compounds. It is a polar solvent and can effectively dissolve other polar covalent compounds by forming hydrogen bonds. Ionic compounds, on the other hand, tend to be soluble in water or other polar solvents that can effectively separate and solvate the ions.
What else can I help you with?
What is the advantage of acetone over ethanol in recrystallization?
Acetone has a lower boiling point than ethanol, making it easier to remove from the crystallized compound. Acetone also tends to dissolve impurities better than ethanol, resulting in purer crystals. Additionally, acetone is less likely to form hydrates with water compared to ethanol, which can interfere with the recrystallization process.
Is MgcI a molecular covalent compound?
No, MgcI is not a molecular covalent compound. It is likely an ionic compound formed from a metal (Mg) and a nonmetal (I) through ionic bonding.
Are ionic compounds more likely to dissolve in water than covalent compounds?
Yes, ionic compounds are more likely to dissolve in water than covalent compounds because they can dissociate into ions when placed in water due to their charged nature. This makes them readily interact with water molecules through ion-dipole interactions, facilitating their dissolution. Covalent compounds generally do not dissociate into ions in water and may not have the same level of interaction with water molecules, making them less likely to dissolve.
What test is commonly used to determine if a compound is ionic or covalent?
The electronegativity difference between the elements in the compound is commonly used to determine if a compound is ionic or covalent. If the electronegativity difference is large (typically greater than 1.7), the compound is likely ionic; if the difference is small (around 0.5 or less), the compound is likely covalent.
Is FeO2 an ionic compound?
No, FeO2 is not an ionic compound. It is more likely a covalent compound based on the elements it consists of (iron and oxygen). Iron can form both ionic and covalent compounds, but in the case of FeO2, it is more likely covalent due to the high oxidation state of oxygen.
What of compound would be least likely to dissolve in water?
A non polar compound would be least likely to dissolve in water.

Which compound is least likely to dissolve in water ionic compound charged compound polar compound or non polar compound?
Non-polar compounds are least likely to dissolve in water because water is a polar solvent and non-polar compounds do not interact well with polar substances. Ionic compounds and charged compounds are more likely to dissolve in water due to their ability to interact with the polar water molecules.
A covalent compound is most likely formed from what type of elements?
A covalent compound is most likely formed from nonmetals or elements with similar electronegativities. This is because covalent bonds involve sharing of electrons between atoms to achieve a stable electron configuration.
Would silicon and nitrogen form an ionic compound?
Silicon and nitrogen typically do not form an ionic compound as both elements are nonmetals and tend to share electrons to form covalent bonds. In this case, they are more likely to form covalent compounds rather than an ionic compound.
Why are covalent compounds often not soluble in water?
Covalent compounds tend to be insoluble in water because they do not dissociate into ions when placed in water. Since water is a polar solvent, it is more likely to dissolve ionic compounds, which do dissociate into ions in solution. Covalent compounds generally have a lower tendency to interact with water molecules, making them less likely to dissolve.
Two nonmetallic atoms react and a compound is formed The compound has what type of bonding?
The compound likely has covalent bonding. In covalent bonding, nonmetallic atoms share electrons to achieve a full outer electron shell, forming a stable compound. This type of bonding typically occurs between atoms of similar electronegativity.
An unknown compound dissolves in water but the solution does not conduct electricity?
If a compound dissolves into water and allows for the conductance of electrical current its said to be ionic and an electrolyte. Sodium chloride (NaCl) or table salt exhibits this property. Sugar is a compound that will dissolve in water but not conduct current. Sugar is not an electrolyte or ionic; rather a covalent molecule.
