Will a compound with a boiling of 68C is likely to be a network structure or in the form of individual molecules?
A compound with a boiling point of 68°C is more likely to exist as individual molecules rather than a network structure. Network structures typically have higher boiling points due to the strong intermolecular forces holding the structure together. Lower boiling points are indicative of weaker intermolecular forces, suggesting that the compound is composed of individual molecules that can easily separate from each other at lower temperatures.

How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
What happens to the molecules when you boil water do they boils off or stay behind?
Whe you boil water, molecules of water "escape" into the atmosphere. The molecular structure of water is unaffected by boiling.
What is the connection between the size of the molecules in crude oil and their condensing or boiling point's?
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
Melting point and boiling point determination can help in identifying unknown compounds by comparing the experimental values with known values in databases. A match can indicate the compound's identity. Additionally, the range of melting point and boiling point can provide information on the purity and molecular structure of the compound.
What is a covalent compound?
A covalent compound is a chemical compound formed by the sharing of electrons between atoms. This type of bond is typically found between nonmetal atoms. Covalent compounds often have relatively low melting and boiling points compared to ionic compounds.
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
What is the boiling point of an ionic compound?
Ionic compounds do not have a specific boiling point because they do not exist as individual molecules. Instead, they have a high melting and boiling point as they require a lot of energy to break the strong ionic bonds between the positively and negatively charged ions.

Nonpolar molecules
How does the presence of hydrogen bonding affect the properties of molecules in a chemical compound?
Hydrogen bonding affects the properties of molecules in a chemical compound by increasing the boiling point, melting point, and solubility of the compound. This is because hydrogen bonding creates strong intermolecular forces between molecules, leading to greater cohesion and stability within the compound.
Many of the macroscopic properties of a compound depend on?
Many macroscopic properties of a compound depend on its chemical structure and the arrangement of its molecules. Factors such as intermolecular forces, molecular weight, and polarity can impact properties like boiling point, melting point, solubility, and conductivity. These properties can provide important information about the behavior and characteristics of a compound.
How does abnormally low pressure affect the boiling point of a compound?
Abnormally low pressure decreases the boiling point of a compound because it reduces the pressure exerted on the liquid, making it easier for molecules to escape into the gas phase. This results in a lower energy requirement for the liquid to vaporize, lowering the boiling point.
Whether a compound with a boiling point of 68C is likely to be a network solid or in the form of individual molecules?
The compound would likely be a network solid because 68 degrees C is 154.4 degrees F, which is a good amount of heat energy to be creating to separate the elements in the compound. Therefore, it is network solid, which requires large amounts of energy to separates the elements within it.
How does change in pressure affect the boiling point of a compound?
An increase in pressure raises the boiling point of a compound because it requires more energy for the molecules to overcome the increased pressure and escape into the gas phase. Conversely, a decrease in pressure lowers the boiling point because less energy is needed for the molecules to escape.
What happens to the molecules when you boil water do they boils off or stay behind?
Whe you boil water, molecules of water "escape" into the atmosphere. The molecular structure of water is unaffected by boiling.
What changes might you see when a compound is formed?
When a compound is formed, new chemical and physical properties can emerge that are different from the original elements. These changes can include differences in color, odor, melting point, boiling point, and reactivity compared to the individual elements. Additionally, the compound may have a different molecular structure and arrangement of atoms than the elements before they combined.
What is the boiling point of a compound?
as far as i know the B.Pt. is defined as " when the vopour pressure of the liquid is equal to the atomospheric pressure then it is said to be the boiling point of the liquid." similarly "when the vapuor pressure of the solid is equal to atmospheric pressure then its corresponding temperature is called melting point of that compound." so a compound may be a low melting one but the same compound may be ahigh boiling liquid. this is due to the inter & intra molecular forces that exists in the molecules. so there is no specific equation that a compound having a m.p. of 102c will have a b.pt. of some particular value.
