Hydrogen is linked by a covalent bond to an atom of oxygen. The covalent bonds are polar, as the oxygen atoms have a slight negative charge.
The type of attraction that holds two water molecules together is hydrogen bonding. The partially positive hydrogen atom in one water molecule is attracted to the partially negative oxygen atom in another water molecule, creating a strong bond between them.
DNA is held together by hydrogen bonding (aka H-bonding).
hydrogen bonds
The bond in water is covalent.
Covalent Bonding
Motor oil is a type of lubricant that typically consists of long-chain hydrocarbon molecules. These molecules are held together mainly by weak van der Waals forces, which are a type of non-covalent bonding.
Hydrogen bonding, dipoles, and London dispersion forces.
Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.
The bond in water is covalent.
Ionic bonding holds the particles together in sodium chloride. In this type of bonding, electrons are transferred from one atom to another, resulting in the formation of charged particles called ions. Sodium donates an electron to chlorine, forming positively charged sodium ions and negatively charged chloride ions, which are attracted to each other to create the sodium chloride compound.
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
The substance is likely held together by hydrogen bonds when dry. Hydrogen bonding occurs between hydrogen atoms of one molecule and electronegative atoms (like oxygen or nitrogen) of another molecule, creating a weak attraction between the molecules.
