Respuesta :
Hydrogen bonding occurs when the hydrogen atom in a molecule is bonded to an electronegative atom. The electronegativity of the atom attracts the electrons present in the bond to move toward it, creating a partial negative charge. Consequently, the hydrogen atom is left with a partial positive charge. These charges cause the molecules to be attracted to one another.
An example of a molecule where hydrogen bonding will not occur will be one where the hydrogen is not bonded to an electronegative atom, such as CH₃Cl (hydrogen bonded to carbon which is not electronegative)

Carbon atom is the least likely atom that would participate in hydrogen bonds in water if present in a molecule.
Further Explanation:
Hydrogen Bond
Hydrogen bond is a type of bond that occurs between a hydrogen atom and a more electronegative atom such as oxygen and nitrogen.
In water for example; hydrogen atoms in a molecule of water have a partial positive charge while the oxygen atom has a partial negative charge.
This results to the formation of hydrogen bonds between molecules of water between partial positive hydrogen atom in one molecule and partial negative oxygen in another molecule.
Other types of chemical bonds
Covalent bond
- This is a type of bond that is formed between non-metal atoms. It is formed as a result of sharing electrons between non-metal atoms involved.
- When atoms involved contribute equal number of electrons to the bond formation, the type of bond is known as covalent bond.
- However, when the shared electrons come from one atom then the bond is known as dative covalent bond.
Ionic bond
- This is a type of bond that occurs between metal ions and non-metal ions. Ionic bond occurs as a result of transfer of electrons from one metal atom to another non-metal atom.
- After the transfer of electrons, metal atom loses electron to form a cation while the non-metal atom gains electrons to form an anion.
Metallic bonds
- Metallic bonds are types of bonds that occur in metallic structure of metals. It occurs between the positively charged nucleus and the negatively charged sea of electrons surrounding an atom.
Dipole-dipole interactions
- It is a type of interaction that occurs as a result of interaction between two polar molecules. The interaction is due to attraction of a partial positive charged atom in a molecule and the partial negative atom in the second molecule.
