Hydrogen bonds
Covalent bonds
The hydrogen bonds between water molecules are weak bonds. They do not involve the sharing or transfer of electrons.
The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.
Covalent bonds exists between atoms within a molecule. And liquids can consist of such molecules. However, covalent bonds are not a type of intermolecular bond (bonds such as van der Waals bonds, hydrogen bonds, etc.). As such, they do not define the bonds present between molecules in liquids.
opposite charges
Water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
The bond between water molecules is known as a hydrogen bond.
The intermolecular bonds between water molecules are hydrogen bonds.
Covalent bonds
Ionic bonds
Polar molecules
The hydrogen bonds between water molecules are weak bonds. They do not involve the sharing or transfer of electrons.
There are no bonds between hexane molecules. There are intermolecular forces, called London Dispersion Forces which attract other hexane molecules.
no. it forms between molecules that have opposite charges.
The hydrogen bonds between water molecules and respectively hydrogen bonds between ethanol molecules are broken by mixing; new hydrogen bonds are formed between water and ethanol molecules - this second process is exothermic.
In molecules, energy is stored in the bonds between the atoms.
Water molecules are linked by hydrogen bonds.
