Which molecular solids has the highest melting point?
if this is from castlelearning its choices 1. H2O(s) 2. Na2O(s) 3. SO2(s) 4. CO2(s) the answer is choice 2 because sodium, Na, is a metal. When a metal is bonded to a nonmetal such as oxygen, an ionic bond is formed. Ionic compounds have high melting points. All of the other are nonmetal which mean they are convalent compounds and covalent compounds have low melting points. JgLy<3 :)
Which molecular solid would have the highest melting?
Diamond would have the highest melting point among molecular solids due to its strong covalent bonds formed between carbon atoms in a tetrahedral structure. These bonds require a significant amount of energy to break, resulting in a high melting point for diamond.
What is the difference between ionic covalent and molecular compound?
Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals.) An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state. A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and cannot conduct electricity regardless of state. Another important difference between the two is that an ionic compound is a crystalline solid at standard temperature and pressure (STP), whereas a molecular compound can be in a solid, gas or liquid state at STP. Molecular compound is derived from combinations of different molecules while ionic compound is derived from inducing electrical current into molecules. if the compound contains a metal bonded to a nonmetal, it is most likely an ionic compound. It the compound contains two nonmetals, it is a molecular compound.
Why are the properties of covalent compounds so diverse?
The diverse properties of covalent compounds arise from the varying strengths of the covalent bonds between atoms, different molecular structures, and the types of atoms involved. Factors like bond polarity, molecular shape, and intermolecular forces can all contribute to the wide range of physical and chemical properties exhibited by covalent compounds.
What is the relationship between the melting point and boiling point of a compound and the compounds bond strength?
Several factors affect boiling point, including the forces between the molecules in a compound. The harder the molecules are holding on to each other, the more energy it takes to boil. Water molecules hold on to each other with hydrogen bonds, so it has relatively high boiling point.So, to answer your question, high boiling points might indicate strong intermolecular forces.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.

Why do ionic compounds have high melting points?
In ionic compounds, there are strong attractions among the ions; therefore it takes a lot of energy to break those bonds.High melting point depends on bond strength. When talking about bond strength in ionic compounds, I mean lattice energy. So the easiest answer is: They have a high lattice energy.The strong electrostatic interactions between ions require a lot of energy to break the bonds.
Does two molecules have the same structural formula?
Yes. This is very common among organic compounds. For example, cyclohexane and hexenes -1, -2, and -3 all have the same molecular formula, C6H12.
Is a molecular compound likely to form from two metals?
No, molecular compounds typically form from nonmetals or metalloids bonding with each other, rather than from two metals. Metals tend to form metallic bonds with each other, where electrons are shared among all atoms in a sea of delocalized electrons.

What is molecular homology?
Molecular homology refers to similarities in DNA or protein sequences among different organisms. These similarities suggest a common evolutionary ancestry and are used to infer evolutionary relationships and trace the diversification of species over time. Molecular homology is a key principle in molecular biology and evolutionary studies.
How to determine the strongest acid among a group of compounds?
To determine the strongest acid among a group of compounds, you can compare their acidity based on their ability to donate a proton (H ion). The compound that can easily donate a proton and stabilize the resulting negative charge is considered the strongest acid. This can be determined by looking at the chemical structure and the presence of functional groups that can stabilize the negative charge.
