When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
When a molecular solid mixes with water do the covalent bonds within molecules break?
No, when a molecular solid mixes with water, the covalent bonds within the molecules do not break. The solid may dissolve due to intermolecular interactions with water molecules, but the covalent bonds within the molecules remain intact.
Does covalent structures have high or low boiling points?
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
How are ionic and covalent compounds different in terms of melting and boiling point?
Ionic (e.g. sodium chloride etc.): highmelting/boiling points. Ionic bonds (electrostatic attraction between oppositely charged ions) must be broken to break the ionic lattice and form a liquid/gas. Ionic bonds are strong so lots of energy is required.Giant covalent (e.g. diamond, graphite, silicon dioxide): high melting/boiling points. Covalent bonds (shared pairs of electrons) must be broken for the substance to become a liquid/gas. Covalent bonds are strong so lots of energy is required.Simple covalent (e.g. water, hydrogen, ammonia, bromine): low melting/boiling points. Although covalent bonds are strong, they do not need to be broken in order to separate molecules and the substance become a liquid/gas. Only weak forces between the molecules must be overcome, which does not require much energy.
Do ionic bonds have the highest boiling point?
No. Ionically bonded compounds have very poor conductivity as there are no free electrons

Why does iron have a higher boiling point than water?
Metals have metallic bonds, water has a covalent bond.

What force is strong enough to break covalent bond of water?
High temperature can break the covalent bond of water by providing enough energy to overcome the bond strength. Alternatively, electrolysis, which involves the passage of an electric current through water, can also break the covalent bonds of water molecules.
Do hydrogen bonds lower the boiling point of water?
No, hydrogen bonds actually increase the boiling point of water. Hydrogen bonds are strong intermolecular forces that require more energy to break, thereby increasing the boiling point of water compared to substances with weaker intermolecular forces.
What type of bonds form within a water molecule?
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
What type of bonds does the water have?
covalent bonds
The boiling temperature of water is so much higher than that of methane because water molecules are?
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
Is covalent bonding soluble in water?
Covalent bonds themselves are not soluble in water because they are intramolecular bonds within compounds. However, some covalent compounds can be soluble in water depending on their polarity and ability to form hydrogen bonds with water molecules.
