Which of the following compounds exhibit hydrogen bonding?
hodyreva [135]

Answer:

a,b,e,f,g

Explanation:

Hydrogen bonding is an intermolecular force of attraction between two molecules. It is a special type of dipole-dipole attraction.

In hydrogen bonding, the hydrogen on one molecule binds with an electronegative atom on another molecule usually oxygen, nitrogen and fluorine.

The simple electrostatic attraction leads to strong intermolecular interaction between two molecules.

 For the formation of hydrogen bond, a hydrogen atom must be bonded to more electronegative specie usually N, O and F

  In H₂O and H₂O₂ ;   hydrogen bonds with Oxygen

       CH₃NH₂; hydrogen is attached to nitrogen

       HF; hydrogen is attached to fluorine

        CH₃OH; hydrogen is attached to oxygen
