WebJan 23, 2024 · First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. It is very important to apply this rule only to like compounds. WebSubstances with small molecules have low melting and boiling points and do not conduct electricity. Giant covalent substances have very high melting points.

How Can You Determine If a Molecule Has a Higher Boiling Point?

WebHigher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a … WebMay 12, 2016 · HF's high boiling point is due to hydrogen bonding which none of the other HX molecules show. The general trend is that BP increase as molecules get heavier due to more electrons and hence stronger London dispersion forces. It's HF that bucks the trend. grand theft auto minigame

Properties of ionic, covalent, and metallic compounds

WebIonic compounds tend to be crystalline structures with high melting points that are water soluble. Covalent bonds are highly stable bonds with low melting points. Many covalent … WebFeb 10, 2024 · 1. Hydrogen bonds are relatively strong intermolecular forces, and thus it takes a lot of energy to break these bonds. This is why the boiling point of water is high, because a lot of heat (energy) is needed to break the intermolecular bonds holding the water molecules together.
